Seed Propagating Anthuriums: Learn About Planting Anthurium Seeds


By: Bonnie L. Grant, Certified Urban Agriculturist

Anthurium plants don’t reliably produce fruit, which can make gathering and growing their seed a problem unless you have another seed source. Cuttings are a far easier way to get a new plant, but if you are up for an adventure, some tips on planting anthurium seeds can help you find success. Propagating anthuriums from seed will also require some tricks to make the tiny flowers fertile, as the stigma and stamen are active at different times. Only some pollen saving and tickling can produce any fruit and therefore any seeds.

How to Get Seed from Anthurium

Anthurium flowers are both male and female with the female flowers coming first. This means that unless you have several plants with flowers in different stages of development and of different sexes, an individual anthurium is unlikely to produce fruit. With no fruit, you have no seeds. In order for anthurium propagation by seed to occur, you will need to solve this problem.

Propagating anthuriums from seed begins with tricking your plant into producing that needed seed. The flowers are first female and then turn into males, which emit pollen. Collect the pollen from a ripe male and store it in the refrigerator. To tell if you have a receptive female, the spadix will be bumpy and may be exuding some liquid.

Get your pollen and a tiny art paintbrush and apply pollen to the swollen spadix. The whole process is a lot easier with several anthurium plants, which develop at different times. This is probably how you are going to have to source seed, as it is not readily available. Anthurium propagation by seed is not the favored method, since cuttings and tissue culture are more common.

After pollinating the spadix, the organ will undergo some changes, gradually. Fruits will take 6 to 7 months to develop. Ripe fruits bulge from the spadix, become orange and are quite easy to pull out of the organ.

The seeds inside the fruits are covered in sticky pulp, which needs to be washed off before anthurium seed propagation. The best way to achieve this is to soak the seed several times, swirling the liquid to help wash off the pulp. When seeds are clean, lay them on a paper towel to dry.

Planting Anthurium Seeds

Anthurium seed propagation requires proper planting and continued care. Flats are good containers for planting anthurium seeds. The best planting medium is vermiculite which has been previously moistened. Lightly press the seed into the vermiculite, leaving an inch (2.5 cm.) between.

Covering the container will speed up germination, as it increases heat and conserves moisture. Place the flat where temperatures are at least 70 degrees Fahrenheit (21 C.), using a seed mat if necessary. Keep an eye on the soil and container, however. If too much moisture builds up, take the cover off for a bit to allow excess moisture to evaporate and the seedlings to breathe.

Once germination is achieved, you can remove the cover. Gently move seedlings to individual containers and follow general anthurium care. These little starts can take up to 4 years to produce the lovely spathe, so just be patient.

Seed propagating anthuriums is not the most popular method due to its proclivities, but it sure will be fun when you have your own crowd of these special plants.

Anthurium Plant Profile

The Spruce / Letícia Almeida

Anthurium is a genus of around 1,000 species of perennial plants native to Central America, northern South America, and the Caribbean. While they can be grown outdoors in the garden in warm climates, anthurium is more often grown as houseplants by enthusiasts willing to put forth the effort for a plant that can be fussy. Some species are highly prized for their bright, exotic flowers, while others are grown mostly for their foliage.

The flowering varieties of these plants are distinctive for their multicolored spathes and red or yellow tail-like flower spikes. Other varieties feature large-leaved, deeply veined foliage. Many anthuriums are climbers and all need high humidity and warmth to thrive. They tend to thrive in greenhouses, and no type of anthurium is particularly well-suited for indoor, domestic living without a lot of attention and care.

Watch Now: How to Grow and Care for an Anthurium Plant


Anthuriums, just like other houseplants, can survive in water as long as you give them what they need to continue growing. Hydroponic gardening is a form of hydroculture where plants grow in water. The process involves rinsing the roots from traces of soils and placing them in water.

Anthuriums are one of the many houseplants that thrive well in water. To place your anthuriums in water, rinse the roots under lukewarm running water until there are no traces of soil left to prevent the roots from rotting in the water. Pick a beautiful glass vase (we prefer transparent vases!), fill it with water about a quarter of the vase, and place your anthurium plant in it.

A glass vase lets you watch your plants grow, plus you won’t have to water them so often.


Basic Plant Care for Anthurium Salgarense

Anthurium Slagarense can grow in a wide range of soils from sandy loams to clay but whichever soil mixture you use, just make sure it is well-draining. If you want to grow it in 100% sphagnum moss, keep it loosely packed in the pot. A fluffy texture will allow for good air circulation.

Any potting mixture that’s porous but has good water retention properties works great for Anthuriums. A porous medium allows the water to run freely. You can use the following materials at equal portions to create a custom mixture:

  • Orchid bark
  • Coarse grade perlite
  • Peat moss

One optional step is to add about 10% charcoal in the above mixture this will help in removing toxicities that build up in the potting soil. Mulching is also necessary for Anthuriums. The preferred growing zones for this plant are USDA hardiness zones 10 to 12.

Watering

Water it frequently in the growing season. Keep the potting mixture slightly moist but not wet for too long. Overly wet soil easily leads to root rot and other issues.

The amount of water also matters, do not drown the plant in water and dispose of the excess water. Increase the watering frequency if you feel the potting soil has dried out.

Check the top few inches before you water if the soil is still damp, skip the watering but if the soil feels crumbly, treat your plant with a good drink.

Water it well every 1 or 2 weeks, but allow it to dry before watering again. You can alter or increase the watering frequency based on light and temperature.

If the potting mixture is too compact, it’s going to take longer to dry out. This is because the lower portion of the soil does not get enough airflow. On the other hand, if the potting mixture is too airy, it might dry out faster than you expect, leading to under-watering.

The aim is to maintain a watering schedule that keeps the roots happy and hydrated according to Dustin’s blog on Aroids, Anthuriums, and Philodendron care. You may have to experiment to find the perfect balance for your Anthurium Salgarense.

In winter, Anthurium Salgarense needs a six-week rest period to reduce the watering.

Light

Anthurium Salgarense is a sun-lover that requires bright but indirect sunlight exposure. Your plant needs at least 10 hours of moderate but continuous light. You can use a combination of natural sunlight and grow lights.

Anthuriums are epiphytic plants that grow on trees. This species can survive in low light, but it seeks bright sunlight because that encourages better leaf growth. They need plenty of energy to grow the beautiful foliage, so bright light is best suited.

I have placed my Anthurium a few feet away from the window to make sure the direct sun rays never hit the foliage.

Surprisingly this Anthurium can tolerate full sun, but I would not suggest that because the foliage may suffer from sunburns.

Temperature

This plant likes warm environments. Keep the Anthurium Salgarense in ambient temperature ranging from 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius).

Even if your plant is grown in a greenhouse, it should be well-ventilated. Avoid draughty doors, windows, and extreme temperature fluctuations.

Humidity

The only thing Anthuriums hate is dry air, so keep your plant in an environment with 65% or higher humidity levels. One of the main drawbacks of growing Anthuriums in low humidity is that new leaves are flawed, and old leaves start dropping.

You can create the desired humid environment for your plant by misting it with room temperature water every few days. Having a humidifier is great if you have several houseplants that like high humidity.

A wet pebble tray is also effective for improving indoor humidity levels.

Fertilizer

Right after you receive your plant, feed it with a diluted vitamin solution to help it recover from transportation shock.

Almost every houseplant needs nitrogen, potassium, and phosphorus content for optimum growth. You can use any standard NPK fertilizer for the Anthurium Salgarense.

I have used 9-3-6 and 12-12-12 water-soluble fertilizers for my Anthurium plants. Prepare a fertilizer solution by mixing 1/2 teaspoon of fertilizer with 1-gallon water. You can apply this solution while watering your plant.

Fertilizing this species bi-monthly in the growing season is more than enough. But in winter, reduce fertilization.

Repotting

I always refresh the potting soil for my plants annually. This prevents several root problems and gives me an opportunity to examine the root ball. You need to repot the Anthurium Salgarense only when the plant outgrows its pot, or the potting mixture is deteriorating. Keep the following points in mind for repotting.

  • The potting mixture takes longer to dry out.
  • There is a decline in plant growth and general health.

I repot all my plants after 1 or 2 years this is true for this Anthurium as well.

Pruning

The Anthurium Salgarense might be small as a young plant, but it grows really fast, taking up a lot of space. To keep it happy and growing, prune the dead or yellow foliage using sharp scissors or pruning shears.

Propagation

All Anthurium species are considered the easiest to propagate. You can grow your Anthurium plant collection with simple cuttings that can be taken while pruning your plant or specifically for propagation. Follow the simple steps discussed below for the successful propagation of your Anthurium Salgarense.

Locate a healthy stem on a mature Anthurium Salgarense plant. Disinfect the gardening tools ( pruning shears or scissors) by dipping them in rubbing alcohol. This is critical for the success of propagation as well as for the prevention of diseases. Using germ-free equipment will protect both the cutting and the original plant.

Stem Cuttings in Soil

  • Make an inclined cut just below the leaf node on the selected stem. The cutting should be at least 6 inches in length. Additionally, the cutting should also have 2 or 3 leaves on it. Remove any leaves on the lower part of the cutting.
  • Dip the cutting in a rooting hormone powderif you want to encourage fast growth and root development. This step is completely optional because fulfilling light, temperature, and water requirements are enough for successful propagation.
  • Take a 10-inch pot and fill one-third of the pot with a well-draining potting mixture. Drainage holes are a must for the Anthuriums.
  • Create a 2-3 inches deep hole in the center of the soil. Place the cutting all the way in the hole and pour some more soil. The leaves should not touch the soil they should be above the surface level of the potting surface.
  • Now water the cutting until the soil is completely saturated. Afterward, only water when necessary but don’t allow the top layer to dry out completely. Anthuriums are native to rainforests, so they want moist soil conditions.
  • Place the pot/container in a bright spot with filtered sunlight and high humidity. Alternatively, you can cover it with a plastic bag to create a small greenhouse for your cutting. But don’t forget to add a few holes for air circulation.
  • Open the bag for 1 or 2 hours every day for air circulation and light supply.
  • Root development will take four to six weeks. Tiny, new leaves on the cutting confirm the root development on the cutting.
  • After that, you can either continue growing it in the same container or shift it to a bigger one. Continue to care for your cutting as a young Anthurium Salgarense based on the instructions discussed previously.
  • If you plan to shift your cutting, allow the roots to grow few inches long before the transfer.

Another method of propagation is the root division. If your Anthurium has outgrown its container, you can split it to have more plants. This should be done when the roots start emerging from the drainage holes or circle the top surface of the soil.

Dividing it to a reasonable size will make your plant healthier with more blooms on it. Simply take the plant out from its pot and, using clean tools, separate the roots. The number of sections will vary depending on the size of your plant.

Blooms

This plant features long, draping inflorescence complementing the dark, metallic green foliage. The blooms are, in fact, spathes that have a foul smell.

Growth

This plant is a holy grail for exotic plant lovers because of the giant leaves. This Anthurium has beautiful, glossy leaves with lobes. The leaves are in shades of light and dark green.

Compared to other Anthuriums, Salgarense has extensive growth and develops particularly large leaves as it matures. This plant can easily grow 8 feet tall when grown in a large pot.


Humidity

In their natural habitat, Warocqueanums are exposed to great amounts of humidity. They are from a family of plants that do enjoy these high humidity levels.

Therefore, a lot of plant breeders jump to the conclusion they have to overwhelm their Queens with great amounts of humidity. Makes sense, right?

What they tend to forget here is that these natural high humidity levels are accompanied by the same amounts of air circulation which is something you can hardly provide indoors.

There’s a common belief that humidity must be 70% and higher. But this goes for the outdoors. Indoors you can water your plant frequently to compensate for high humidity.

If the humidity of the room where your Queen lives is not below 55% there is no need to buy a humidifier.

Alongside humidity goes the temperature, and it is the balance of the two that is important.

The optimal temperature for all Anthuriums is between 20 and 25 Celsius.

Warocqueanum is a tropical plant and it grows in a hot and humid climate. But don’t obsessively strive to replicate these condition. Because it is, to put it simple – impossible.

Instead, allow the plant to adapt a little. It won’t tolerate a huge discrepancy of course, but a minor difference may be beneficial.

If you are planning to buy the Queen do it in the summer, so it can adapt with less trauma to the new environment.


As your plant grows, you will notice roots that are growing out of the pot and into the air. These are known as aerial roots. They are common in plants that grow in trees as an adaption to life above the ground. It’s just another way that the plants reproduce. You can just push these roots back into the soil or you can cut them off to make new plants. Dip the cut ends in rooting hormone and gently push them an inch or two into a pot filled with the same soil-less mix that the parent plant is growing in. The root will start to develop stems and leaves within 4 to 6 weeks.

Anthuriums are easy to grow from cuttings. Choose a stem that is at least 6 inches long and has two or three sets of leaves on it. Dip the cut end of stem in rooting hormone and then gently push it up to the first set or leaves into the same soil-less mix that you use to grow your plants in. Water the cutting thoroughly and then water as you would an established plant, allowing the soil to dry slightly between waterings. Mist your cutting weekly to provide humidity. Your cutting should develop roots within 4 to 6 weeks. You will know that roots have grown by the new growth on the top of the plant. Plants cannot produce new growth if they have no roots so new leaves are an indication that your cutting has started to grow roots.


About Anthuriums

The anthurium plant is also commonly known as the flamingo flower. But, it likewise has other nicknames like tailflower and laceleaf.

Also, it’s also worth noting that there are over 1,000 different species of anthuriums around. So, don’t be surprised to see a few that don’t resemble what you’re familiar with.

That said, these plants are known for their beautiful bright colors and unique looking shapes. You’re likely familiar with their red and yellow colors since they’re often used in cut-flower arrangements.

Better yet, they can bloom at any time of the year lasting as long as 2 months.

What many people don’t know is that there are actually some species better known for their foliage rather than their blooms. Unfortunately, they’re often overshadowed by their more showy counterparts. As such, you’ll usually find them in specialty nurseries.

Anthuriums usually grow up to only 12 to 18 inches tall. Thus, they’re fairly compact making them good houseplant options. This makes them perfect in tall pots on tabletops.


Why is my anthurium leaves getting yellow?

If you notice your anthurium leaves turning yellow, the most probable reason is lack of sunlight. Is its current location a little darker? If yes, then, you have to move it somewhere well-lighted. Just avoid having directcontact with sunlight to avoid scorching the leaves.

How to care for anthurium cut flowers?

Assuming you have several varieties of anthurium and they finally bloomed with different colors, you may use the flowers and arrange them together in a single container. This will make an exquisite flower arrangement.

All you need is cut the mature flowers at the base of stem. Prepare a vase with clean water on it and place the cut flowers there. You may add other cut flowers and accessories too.

Replace water once a week. Cut the stem at least 5 cm off the base every time. Anthurium cut flowers can last two to three weeks if it’s well taken care of.

Why is my anthurium plant not producing flowers?

If the growing conditions are not ideal, you’ll have trouble encouraging your anthurium to bloom. The key is enough bright light. Growing anthurium in the dark will only produce foliage.

Another way to make it bloom is regular fertilization. Using liquid fertilizer that’s high in phosphorus will help the plant produce more flowers as well.
