Anthurium or Laceleaf

Anthurium plants belong to the Anthurium genus, also known as anthurium, tailflower, flamingo flower, and laceleaf. This genus is the largest in the family Araceae and contains more than 1,000 species. It grows as an epiphyte or semi-epiphyte, in rock crevices or on shallow, skeletal, limestone soil. This genus includes both epiphytic and terrestrial plants. The genus is native to the Americas, where it is distributed from northern Mexico to northern Argentina and parts of the Caribbean. The name Anthurium comes from the Greek words anthos – meaning flower, and oura – meaning tail.



These exotic plants are better known as the flamingo flower due to the frequent fiery color of their heart-shaped wax flowers. The stunning, large leathery leaves are usually heart-shaped, oval, or elongated. Many anthuriums are climbers, and all need high humidity and warmth to thrive. Anthurium is an attractive species for all collectors of rare and exotic plants. All Anthurium species are poisonous due to calcium oxalate crystals. The sap is irritating to the skin and eyes.. Most poisoning symptoms disappear after a while, but it is still recommended that you keep them out of the reach of children and pets.

Growth Nutrition of Anthurium


Like all plants, anthurium plants require certain nutrients in order to grow. The absence of these nutrients can cause your plants to grow slower or even die. Proper anthurium care dictates giving your plants the correct amount of each of these nutrients. The three main nutrients required by anthurium flowers and all plants are nitrogen, phosphorus and potassium. Nitrogen stimulates stronger green growth, Phosphorus is the element most responsible for stimulating stronger bud, fruit and flower development and Potassium, is vital to several areas of plant growth.


Magnesium is another vital nutrient. Without it, your plant will be stunted and its leaves will begin to turn yellow and start dying. In addition, a lack of magnesium will cause new leaves to be deformed. Calcium is also very important. Lack of calcium can cause the flowers of your plant to die. Calcium deficiency will cause new leaves to be deformed and will also distort the edges of mature leaves. If the deficiency continues, the leaves will start turning yellow and begin dying.


Sulfur is another important nutrient. Lack of sulfur will result in slight stunting of your plant and slight yellowing of its leaves. Your plant may be able to survive a sulfur deficiency, but why take any chances?


Types of Anthurium


The most popular types of anthurium:

  • The flamingo flower (Anthurium andreanum) with its lipstick-red waxy flower and shiny heart shaped foliage.

  • Anthurium scherzerianum looks similar to the flamingo flower but has a curly spathe resembling a pig’s tail.

  • The velvet cardboard anthurium (Anthurium clarinervium) with large deeply lobed leave and veined patterns.

  • Black anthurium (Anthurium watermaliense) has flowers that are deep purple, almost black-looking.

  • The bird’s nest (Anthurium hookeri) has large dark-green elongated leaves.


Anthurium Varieties:


Anthurium Andraeanum



Athurium andreanum is aparticularly popular houseplant. Also known as the flamingo flower, flamingo lily or painter’s palette, Athurium andreanum has heart-shaped leaves that grow up to 40 cm wide, and a flower bulb that is enclosed in a colourful bract. The colour of this bract depends on the plant’s variety.


Almost every flowering plant sold as an Anthurium is from one species: the ubiquitous Andraeanum. Common names include Flamingo Flower or Laceleaf, but this massively popular species become simply “Anthuriums” to retailers and home gardeners worldwide. They are easy to care for and capable of almost continuous bloom.


The flowers are actually large, colored leaves. They often appear lacquered. Most blooms are long-lasting, staying fresh-looking for at least several months. They have a center spike, or spadix, which holds tiny flowers; the colorful part we consider the flower is actually a modified leaf called a bract or spathe.


Andraeanums come in different colors, sizes, and bloom shapes, including ribbon-, tulip-, and cup-shaped flowers. Even if you only grow this species, it can be a diverse collection.

Here are special hybrids in high demand:

  • Anthurium Andraeanum ‘Oaxaca’

  • Anthurium Andraeanum ‘Champion’

  • Anthurium Andraeanum ‘Zizou’

  • Anthurium Andraeanum ‘Livium’

  • Anthurium Andraeanum ‘Purple Miss June’

  • Anthurium Andraeanum ‘Simba’

  • Anthurium Andraeanum ‘Black Beauty’


Anthurium Scherzerianum



This enormously popular species looks a lot like an Andraeanum, with one outstanding difference you can spot across the room: it has a decorative, curly spadix. The leaves are also more elongated and lance-like, tapering to a narrow point.


The Scherzerianum, or Pigtail Anthurium, was popularized even earlier than the Andraeanum. It is especially well known in Asia and parts of Europe, but they’re a little more elusive in North America. Overall, its care needs are similar to the hardy Andraeanum.


An amazing assortment of cultivars exist with flowers of red, orange, pink, purple cream, or green – some have a combination on each bract! The coiled spike can be a matching or contrasting color.


With so many cultivars being bred, the retail names are not always strictly applied. This makes it challenging to find a specific variation, but the abundance means you’re sure to find one to love.


Anthurium Amnicola (Tulip Anthuriums)



Tulip Anthuriums are smaller and more compact than Andraeanums. They make excellent indoor specimens and are just as hardy and easy to care for as their larger relatives. They exhibit resistance to aroid blight, too.


Here are some of the most popular Tulip anthurium varieties:

  • Anthurium Amnicola ‘White Lady’



This elegant variety has slender, pure white flowers that look like a brilliant Peace lily with upright bracts forming a charming background to their white spadix. Their spathes are especially long-lasting. Smaller than most Anthuriums, the White Lady graces any bright corner.

  • Anthurium Amnicola ‘Lumina’

This beautiful variation on a white scheme features prominent, intricate longitudinal colored veining over snowy bracts. The flowers display a subtle gradient, too.


The Lumina’s leaf shape is wavy, as if it were rippling in the wind. The long, narrow spadix stands out in hues of purple or maroon.

  • Anthurium Amnicola ‘Lilli’

One of the most tulip-like varieties, the Lilli has vibrant, pink-colored flower bracts nestled in lush green foliage. Both the flowers and leaves are narrow and ribbon-shaped and point upward. It looks wonderful in a pot and even more amazing in mass plantings.


Anthurium Superbum



Now we step from flowering Anthuriums into exotic foliage Anthurium varieties, and the Superbum is a great species to start with. The plant has broad, rounded, textured green leaves with sepia-toned undersides that grow to about 18 inches long. Arranged in a centralized, upright growth pattern, the foliage has a sculptured, prehistoric look.


Typically living as an epiphyte in the wild, the Superbum’s leaves form a bowl that invites nesting birds – or, at least, collects dead foliage and other forest matter. The plant’s strategy is to capture nutrients from the decomposing material.


Birds-nest Anthurium varieties are among the more resilient options but don’t use heavy soil or let the mix get soggy. Some growers recommend giving birds-nest Anthuriums a short dry period during the year.


This plant used to be a high-dollar find, but its popularity has led to higher production and a lower price tag. The Superbum has a lot of character and makes an interesting but low-drama houseplant.


Anthurium Hookeri (Bird’s Nest Anthurium)



The Anthurium hookeri has the common name ‘bird’s nest’ even though other species have a similar growth pattern. This evergreen tropical plant is grown for its foliage rather than its green flowers. The shiny green leaves are an elongated oval shape that sometimes resembles a huge spoon. The anthurium hookeri also has characteristic tiny black dots on the green leaves that help to identify the species.


Bird’s nest anthuriums grow well in large containers indoors or as tender patio plants in temperate climates. When the anthurium is in bloom, it produces long purplish spikes (spadices) that stand erect. After blooming, small white berries appear on the spadix.


Anthurium Clarinervium (Velvet Cardboard Anthurium)



Anthurium clarinervium, also known as the heart leaf plant, looks confusingly similar to Anthurium crystallinum. Both species have dark green, heart-shaped leaves that display a beautiful white vein pattern. However, the two species can be distinguished by the colour of their berries; each produces fruit on their flowering bulbs. Like most anthuriums, this species prefers a bright location, but not full sun, as this can cause the leaves to burn.


They are sometimes even called the White Venous Anthurium. Anthurium Clarinervium is a stunning tropical species native to the rainforests of Mexico.


Anthurium Crystallinum (Anthurium Ace of Spades)



Anthurium crystallinum is known for its dark green leaves and striking white vein pattern. Its heart-shaped leaves can have a purple tinge at first before turning green as they develop, while its flowers are quite subtle. In its native South America, Anthurium crystallinum usually grows as an epiphyte, perched on trees or other plants. As such, it is best to plant this anthurium in loose orchid soil. Its aerial roots are not adapted to life in standard potting soil. Ace of Spades is a permanently flowering plant that can decorate your home all year round.


Anthurium Magnificum



Like the look of Anthurium clarienrvium and Anthurium crystallinum, but think they are a bit too small? Then Anthurium magnificum is the plant for you! The foliage of this species is similar to its two relatives, but the plant can grow much larger. In fact, it may need a support to grow up against.


Anthurium Forgetii



Anthurium forgetii is not known for its coloured bracts, but for its small, round leaves that taper to a point. These green leaves are either patterned with white veins, or plain. In keeping with its tropical, epiphytic nature, Anthurium forgetii prefers high humidity and loose orchid soil.


Anthurium Regale



This is a spectacular bright-veined Anthurium. Its mammoth heart-shaped leaves are brilliant green and have stunning white veins radiating outward from the central line. One of the largest Anthuriums in existence, their foliage grows four feet long or more in ideal conditions.


The Regale’s requirements are up for contention. Some growers say they need cool temperatures to thrive, others claim they grow at 70ºF (21ºC) and above – all agree high humidity and moisture are important. It’s definitely a plant for more experienced collectors.


This Peruvian species isn’t a fast grower, but it responds to the right environment. Each leaf increases size between four to six inches as the plant grows. They become truly breath-taking over time.


Anthurium Faustomirandae (Faustino’s Giant)



Anthurium Faustomirandae is a species often referred to as the largest Anthurium in the world. Anthurium Regale is the largest species in the Anthurium genus, but Faustino’s Giant is considered to be the largest species native to Mexico.


Anthurium Whitelockii was the name of this huge species until it was officially named Faustomirandae.


Magnificent heart-shaped leaves can reach an incredible 9 feet. The texture of the leaves is glazed and they are very thick and durable.


The stalks are also large, holding the magnificent green flowers with a chestnut-colored seedling. This rare terrestrial species is easy to grow and makes a perfect landscape tropical plant.


Anthurium Coriaceum



This is one of the most attractive species, also called the Paddle Leaf. It can reach an amazing height of 3 feet. It has very rich green velvety, erect, and paddled leaves.


This species is recognized by the pronounced middle vein on the back of the leaves. The flowers are also green with a brown spade. Anthurium Coriaceum is a native to the humid rainforests of Brazil.


Anthurium Gracile



This Anthurium is one of the few species whose fruit is part of its appeal. It is commonly called the Red Pearls Anthurium for the bright red berries it produces along its spadix. The fruit adds a bold dash of color to the paddle-shaped leaves splaying out on their petioles.

Even though their actual roots are short and chubby, the plant’s aerial roots can hang down three feet or more. These roots and sprawling stalks give the Gracile a messy, wild look as it matures.


This is one the easier rare Anthurium varieties to maintain: they thrive in a range of light levels and adapt to average humidity. It’s a true epiphyte that thrives in soil suitable for orchids.


The Gracile is an uncomplicated variety with a unique twist. They aren’t common and may require a search, but they are (currently) reasonable.


Anthurium Warocqueanum (Queen Anthurium)



Queen anthurium (Anthurium warocqueanum) looks quite like Anthurium crystallinum. Here too, the plant has dark green leaves, eye-catching white vein patterns, and subtle flowers. With the right care, the lance-shaped leaves of queen anthurium can grow up to two metres in size, which is why the species is known as the “queen of anthuriums”. In keeping with its native habitat, Anthurium warocqueanum likes bright, humid conditions.


Anthurium Veitchii (King Anthurium)



The Anthurium veitchii species is also known as the “king of anthuriums”. As with Anthurium warocqueanum, the leaves of king anthurium can grow very large. They are also lanceolate in shape, but display ridges instead of a white vein pattern. This anthurium likes a warm, humid climate and grows epiphytically in nature, which is why its roots prefer a very aerated substrate, such as orchid soil.


Anthurium Vittarifolium



Anthurium vittarifolium has long, green leaves that hang from the plant like tails. This makes it ideal for a hanging basket. In its tropical home, Anthurium vittarifolium is an epiphyte, meaning it grows on other plants and trees from which its leaves can then hang.


Anthurium Metallicum



This anthurium has particularly dark green leaves, which are lightly veined and lance shaped. The leaves look similar to a knight’s shield, and hang down on the end of long stems. The plant can reach 40 to 50 cm tall, and grows hemi-epiphytically in South America. This means that it begins life perched on other plants and, as the roots grow, the plant touches the ground and uses it as an anchor. As such, growing the plant in orchid soil is good for growth, but not absolutely necessary.


Anthurium Polyschistum



Anthurium polyschistum has a subtle flower and leaves that are plain and split. In fact, the leaves resemble hemp, which is why this plant is also called “false marijuana” or “faux marijuana”. Anthurium polyschistum climbs upwards and does not let its leaves hang. It needs humidity and indirect light, as well as moist, slightly acidic soil to thrive. The soil should not be too rich in nutrients. We recommend mixing sphagnum moss with a high-quality potting soil.


Anthurium Bonplandii



Anthurium Bonplandii was divided into several subspecies. Guyana is one of the most famous subspecies that grows in the shape of a bird’s nest. It originates from the Guyanese mountains of Venezuela, but can also be found in northern Brazil, and Suriname.


The unusual Anthurium Bonplandii can be distinguished by its thick and large leather foliage. Anthurium Bonplandii subspecies Bonplandii usually has elliptical leaves, while the subspecies Guyana has lanceolate leaves that extend along the apex, or oblong leaves, wider in the middle part.


Anthurium Clavigerum



Anthurium Clavigerum is considered one of the largest epiphytes in Central America. These plants can reach great heights. In mature plants, the inflorescence can reach 3 feet. This species is rarely confused with any other Anthurium species in Central America.


They are recognized by the ornamental leaves and huge pendant flowers. The leaves are increasingly curling and dividing as they mature. A. clavigerum can be found from Nicaragua to Guyana, Brazil, and Bolivia.


Anthurium Watermaliense (Black Anthurium)



Black anthurium is the most unusual ornamental variety. The dark-colored flowers are highly valued for their uniqueness. This species attracts the eye with its bright green leaves and shiny black leathery cover.


When a bud forms, it is not as dark, but gradually darkens over time. We can thank the growers and botanists for the creation of Anthurium Black Queen.


This is an artificially grown variety, but in any case, the burgundy-black flower is outstanding. It is often called the Black Prince because the flower is considered masculine.


Anthurium Pendulifolium



As its botanical name suggests, the Anthurium pendulifolium has long pendulous leaves that dangle downward. The long tapering green leaves make this species of anthurium suitable for hanging baskets. The shiny leaves measure a few inches wide but can grow up to 4 ft. (1.2 m) long.


The flowers on this anthurium species are inconspicuous. The spadix looks like a long purple spike. However, the spathe is pale green or creamy white and not noticeable.


Anthurium Luxurians



Another unusual species of anthurium is Anthurium luxurians. Its leathery, heart-shaped leaves have deep-ridges that make it look like the surface of a diamond. Sitting on the end of short stems, these leaves are usually very dark red or purple and tend to change with age, from dark red to dark green. Anthurium luxurians grows best in partial shade and well-drained soil. A mixture of well-draining potting soil and orchid soil made from pine bark and Sphagnum moss is ideal.


Anthurium Radicans



Hybrid with extraordinary characteristics originates from southeastern Brazil and some parts of Ecuador. It is a tropical epiphyte that is found naturally growing on trees in the rainforests of Brazil.


The spacious and heart-shaped leaves of Anthurium Radicans add to its uniqueness. The leaves are bright green and distinctly fibrous.


This perennial plant also has exotic, ostentatious deep pink or maroon flowers. The strikingly shaped leaves have classified this plant as a symbol of hospitality and this makes it a popular choice as a houseplant or for growing in home gardens.


Anthurium Scandens (Pearl Laceleaf)



The pearl laceleaf anthurium is a climbing vine plant that is native to rainforests in Southern Mexico and Brazil. The plant has thick, matte green leaves that are oval to lance-shaped. These evergreen leaves grow to between 2.3” and 5” (6 – 13 cm) long.


The bract or this anthurium variety is light green and insignificant with yellowish-green spadix that turns to small white berry like fruits. The fruit looks like a cluster of white pearls, hence its common name pearl laceleaf. This plant makes quite a show when several clusters of these pearly white berries are hanging from the stems.


Anthurium Pachyneurium (Big Red Bird Anthurium)



The Anthurium pachyneurium is another type of bird’s nest plant. This species has broad, long, lanceolate leaves with very short stems (petioles). One of the distinguishing features of this tropical plant is the wavy edges of the leaves. This anthurium species is an excellent specimen plant for containers if you want to bring some of the tropics into your home.


This anthurium variety has a typical rolling pattern of its new leaves – whereas new leaves of other anthurium varieties resemble a single spiral, those of the Pachyneurium type are rolled in two opposite spirals that are rolled inward from both margins.

The common name of the ‘big red bird’ anthurium comes from the color of the leaves that turn reddish in bright light or cool temperatures.


Planting and Growing Anthurium


How to Plant Anthuriums

  • Use well-draining soil with lots of organic matter.

  • Anthuriums prefer bright but indirect light. In direct sun, they may dry out too much and leaves may develop brown, burnt tips.

  • The plant prefers a location with temperatures between 60° and 85°F (15.5° to 29°C).


How to Grow Anthurium From Seed


You can also grow anthurium from seed; however, it can take up to four years before you see flowers, which might discourage those looking for a colorful plant. The best planting medium is for this seed is moist vermiculite. Lightly press the seed into the vermiculite an inch apart. To speed up germination, cover the plant with a clear plastic bag. Place the plant near a window, but no direct light. If the water beads up within the plastic, open one side and allow some air; the plant needs to breathe. Remove the plastic cover entirely after you notice new growth.


How to Get Anthurium to Bloom


Anthuriums are picky. But, their uniquely beautiful flowers make them worth the extra effort. Each flower can last for about six weeks, and they may return, flowering every few months. You might not see blooms If your plant has soggy soil, insufficient lighting, or your plant is too rootbound. You will need high humidity and weekly feeding with a high-phosphorus fertilizer to get this plant to bloom. You can try to tweak other conditions, including using a different potting mix (orchid mix is good) and removing plants from nearby drafty windows or HVAC vents.


Anthurium Care


Anthurium plants thrive in bright, indirect light, and they do not like exposure to direct sunlight, except in the winter months or in plants that have been carefully acclimated. Wild anthuriums generally live in temperatures at or above 60 degrees Fahrenheit, and the foliage types prefer temperatures even warmer. If temperatures dip below this level, the plant will suffer.


Potted anthuriums prefer a rich but well-draining potting mix that should be kept moist but not wet. Potting mix tailored for orchids, with a few handfuls of sand and a few handfuls of peat moss mixed in, is ideal.


Many anthurium plants are "epiphytic" in natural settings—they grow on other plants instead of in soil. If your plant fails to support itself, give it a stake or small trellis to climb on.


Light


Indoors or out, anthuriums grow best in bright, indirect light. Avoid direct sun, which can burn the leaves.


Soil


Anthuriums prefer coarse, well-draining potting. An orchid mix with additional sand and peat moss mixed in makes a perfect potting mix for anthuriums.


Water


The soil should be kept slightly moist and never allowed to dry out completely. Set the pot in a tray with rocks or gravel that has water. The plant's water can drain there and help keep humidity levels higher around the plant. Allow the top of the soil to dry out to the touch before watering again. Indoors, this is about once a week. If outside, during hot days, it can be every two or three days between waterings.


Temperature and Humidity


All species of anthurium are native tropical plants, and mimicking those conditions will give you the best chances for success. This plant prefers high humidity and temperatures between 65 and 85 degrees Fahrenheit. These plants can be grown outside in zones 11 to 12 and will likely perish at temperatures 40 degrees or less.


In dry climates—or during dry winter months—mist the plant daily to keep humidity levels high. You may find it necessary to run a humidifier constantly during dry months.


Fertilizer


It is safe and recommended to use liquid fertilizer throughout the growing period. Use a fertilizer high in phosphorus, dilute it to 1/4 strength and feed the plants every week. The phosphorus-rich fertilizer will help encourage blooms. The common gardening expression, "Weekly, weakly" applies to how often to fertilize and the strength or concentration of fertilizer to water.


Pruning and Propagating Anthurium


Pruning


When a plant has dying or wilting leaves, it puts its energy into trying to revive those dying leaves. You can help your plant focus its energy on creating new leaves and flowers by removing the browning leaves. If they're not easy to pluck, use hand pruners to trim them. Remove faded flowers by snipping them off at the base. Only leave faded flowers on longer if you want the plant to produce seeds.


Take some time to shape your plant; snip off errant leaves or shoots that make the plant look off-balance. Do not remove too many leaves; leave at least three or four.

Propagating Anthurium


Anthuriums have a way of telling you that they're ready to propagate; they send out "air roots." Anthurium roots are fleshy, appearing almost knobby or tuberous. They'll start jutting out from a stem above the soil line in the pot. This can happen during any season. Propagating is a good idea for plants that have stopped blooming or decreased bloom frequency. You can propagate from air root cuttings or stem cuttings—here's how:

  1. You'll need a clean pot, fresh well-draining soil, and a sharp, sterilized knife or pruners. Optionally, you may want to use rooting hormone, to increase your rooting success.

  2. Using your sharp implement, cut off the air roots or select a stem at least 6 inches long with two to three sets of leaves. Dip the cut end of the stem in rooting hormone, if you want.

  3. Plant the cut end of the step or the air root in fresh potting mix. Water the soil thoroughly, keeping the soil moist. Place the pot in a warm spot but with indirect light. It should take about 4 to 6 weeks before you notice new growth.


Potting and Repotting Anthurium


When an anthurium fills its pot with roots and begins to send plentiful air roots, it is time to repot. Usually, this is necessary every two years or so. Transfer the plant to a pot that is only slightly larger than the old one—no more than 2 inches larger.


Get a container based on your watering habits. Overwaterers should get a terra cotta pot that can allow the water to seep out of the container. If you tend to forget about your plants, use plastic or ceramic to hold in moisture. No matter your habits, you need a container with multiple drainage holes.


To repot an anthurium, fill the new pot with about 1/3 potting mix, then set the plant onto the soil and lightly pack additional soil around the base, up to the level the plant was buried in its old pot. As new air roots form above the soil over the following weeks, lightly pack additional potting mix around the exposed roots.


Overwintering


Anthurium will not survive outside in non-tropical zones during the winter. If your plant lives outside for the winter, bring it in as soon as the temperature drops below 60 F. The plant will need a sunny window, temperatures that hover around 75 F, and high humidity. A bathroom environment is perfect for this plant.

Pests and Diseases


Insect Pests


Aphids, mites, thrips, and mealybugs are the most common insect pests for anthuriums and other household plants. If the infestation is still low, you can pluck the pests manually or using home remedies. The use of soap and water to wash the plants is one of the home remedies for small infestations.


However, as the infestation progresses, remember to isolate the infested plants and clean all the gardening tools. Another control measure would be the use of pesticides. Some pesticides are household plants friendly and are readily available in the market.


As a general rule in using pesticides, read the recommended rate and make sure to follow the instructions.


Diseases


Anthuriums are commonly affected by fungal and bacterial diseases, which are commonly seen in masse. Here are the most common diseases:


1. Black Nose Disease


Brought upon by the fungus, Colletotrichum gloeosporioides, this disease causes the blackening of the spadix and it can progress to rotting of the whole spadix. Also, leaves and stems may be affected during serious infestations. It is prominent in humid areas wherein the fungus gets inside the plant’s system through cuts and damages.


2. Rhizoctonia Root Rot


Rhizoctonia solani is the causative organism of this disease, which lives in soils and could survive there for years despite the lack of a host. Your plant might have this if it exhibits symptoms such as early death of younger stems or mushy stems.


3. Phytophthora and Pythium


The fungal pathogens for this disease are the Phytophthora nicotianae var. parasitica and Pythium splendens. Common symptoms of this disease include yellowing of the leaves and root damage. If it gets worse, black lesions on the leaves may be seen. Also, you will observe that the plant does not grow despite giving all the necessary growing requirements.


4. Bacterial Wilt


Caused by the bacteria, Ralstonia solanacearum, this disease makes the anthurium’s foliage yellow during its early stages. As the disease progresses, it destroys the plant’s vascular system making the stems brown and mushy. To know if it’s caused by a bacteria, cut an infected part and dip it in a clear glass filled with water. Observe closely to see bacterial ooze.


5. Bacterial Blight


Xanthomonas axonopodis pv. dieffenbachiae is this disease’s causal organism. It makes the plant’s foliage turn yellow and dull. Also, there are noticeable mushy brown lesions on different parts of the leaf. This disease occurs in moist environments, especially if there are stagnant droplets of water on the surface of the plant.


Control for Anthurium Diseases


Since the mentioned diseases are spread in a moist environment, remember to keep the plant surfaces dry and avoid overwatering. Pasteurization of the soil is also crucial to make sure that soil-borne diseases are killed. Another way to prevent the spread of diseases is by isolating infected plants and cleaning garden tools after usage.


The use of chemical pesticides may bring benefits especially for anthuriums in large numbers. There are protective fungicides present in the market too.


Common Problems With Anthurium


This plant has some special needs, but once you figure out its sweet spot and you nail down a routine, anthurium is an easy plant to keep.


Yellowing Leaves


Too much direct sunlight may cause Anthurium leaves to turn yellow. Bleached and brown tips also indicate that it is receiving too much light. Move the plant a little further away from the window. Also, yellowing leaves can be bacterial wilt. It can change the color of stems and leaves from yellow to bronze.


Deep Green Leaves


An anthurium may also be getting too little sunlight. Dark green foliage is a clear sign. Relocate the plant to a sunnier location.


Floppy Leaves


Rhizoctonia is a fungus that can take hold in roots and lower stems. It makes young, delicate stems weak and floppy because they're waterlogged.


Benefits of Anthurium Plants


Air Purifying Properties


In 1989, NASA released research that detailed the ability of several common houseplants to remove toxins from the air. A. andraeanum was among the plants studied, and the results show that Anthurium can help improve indoor air quality.


How does this work? Indoor air often contains harmful contaminants, such as carbon dioxide, formaldehyde, benzene, toluene, and trichloroethylene. The study also found that indoor plants can help reduce pollutants like cigarette smoke and organic solvents. Anthurium was found to be especially good at reducing the amount of formaldehyde, xylene, and ammonia in the air.


Benefits of Anthurium Plants in Feng Shui


In the spiritual and aesthetic practice of Feng Shui, Anthurium can be used to attract positive energy. Consider placing the plants in a southwestern location within a room or your house. Here, they can both facilitate good fortune and good relationships and ward off sha, or negative energy.


Anthuriums are also associated with wealth, thanks to their red spathes and yellow spadices. The strategic placement of these colorful plants in the home is thought to promote prosperity.


Low-Maintenance and Easy Care


Anthurium plants are easy to care for and don’t require much maintenance, especially when they’re provided with the optimal growing environment. They grow slowly, so they don’t need much feeding and only require repotting every two or three years. Plus, they’re not bothered by many pests or diseases.


The key is replicating the conditions of their natural habitat, the dappled, warm, and humid tropical rainforest. Of course, you don’t want the inside of your home to be 85 degrees F with 90 percent humidity.


Ornamental Value


Anthurium plants have fantastic ornamental value and add a tropical aesthetic to any space. That’s one of the main reasons they’re so popular, even making the Forbes list of top indoor plants. Their foliage is deep green and glossy year-round, with attractive, softly rounded margins.


Anthurium blooms throughout the year with attractive, colorful spathes. These heart-shaped, waxy blooms bring color and shine to the room. Their upright yellow spadices add a touch of drama and texture that draws the eye.


Easy to Propagate


Propagation offers an inexpensive way to grow your indoor plant collection. Anthurium is easy to propagate through division.


Help Ease Allergies


If you experience allergies, adding an Anthurium to your home may help ease your symptoms. Studies show that indoor plants can help remove microbes and pollutants, such as mold spores, from the air. Some of these contaminants play a role in allergies.


Indoor plants like Anthurium can also help boost the humidity level in the air. This can cause contaminants, such as pollen to fall out of circulation. Try placing an Anthurium near your bed or desk and see if your allergies subside.


Reduces Stress and Improves Mental Health


Simply having plants around can help lower stress levels, which may help improve mental health. Studies indicate that looking at green foliage help people feel calmer.


For instance, a study of stress levels in high school students looked at two groups: One attended class in a room with plants, and one in a room without plants. Students in the plant-filled classroom reported lower levels of stress and anxiety.


Simply having flowers in the home or workplace boosts happiness levels. Even looking at pictures of flowers can help people feel better and relieve stress! Studies show that looking at flowers has physiological effects, including lowered cortisol (stress hormone) levels and a drop in blood pressure.


Boosts Productivity and Memory


Plants can even boost productivity. Research indicates that employees in plant-filled workplaces are more emotionally, cognitively, and physically involved with their work. This resulted in 15 percent higher productivity levels.


Similarly, studies show that people are better able to complete tasks and have enhanced concentration when they’re around plants. In spaces with ornamental plants, employees are more accurate and produce higher quality work. Simply being outside in nature has been shown to improve memory and concentration by 20 percent!


Filter Odors


As research shows, indoor plants like the Anthurium help purify the air through a process known as phytoremediation. Along with removing harmful pollutants, plants may filter out contaminants that carry unpleasant odors.


Cigarette smoke, solvents, and other substances that simply don’t smell great — like the volatile organic compounds released by carpet, paint, adhesives, and other building products — tend to linger in indoor air. But thanks to plants’ purifying abilities, these unpleasant scents can be filtered out.
