Native to South and Central America, the Anthurium has around 800 different species.
However, the two most often cultivated species in the United States are A. scherzerianum and A. Andreanum, more commonly known as Laceleaf or Flamingo Lily.
Known for the longest living bloom of any plant, a patient gardener can maintain a flower on an Anthurium year-round. Moreover, who wouldn’t want to?
Their flowers are one of the most interesting of any plant, too. The bloom is red, heart-shaped, has another leaf’s appearance, and is set off with a long white or yellow spathe.
Since they are tropical plants, they’re only considered hardy in USDA zones 10-12. Fortunately, Anthurium does well as potted plants, so no matter what zone you live in, you can enjoy their beauty all year long.
How to Grow Anthurium
Anthurium can be started from seed, cuttings, aerial roots, or division. The soil should be coarse, drain well, and be slightly acidic. Use a pot just a bit larger than the plant, filled about 1/3 of the way with a coarse soil medium. Water lightly and place your Anthurium in a warm area receiving indirect sunlight. Let your plant dry out between waterings for the best results.
The Best Soil for Anthurium
A combination of pine bark, peat moss, and perlite works well for Anthurium as it is a coarse mix that drains well. In addition, the peat moss adds the necessary acidity that your plant needs.
Because your plant will get very little nutrition from the soil mix, you will need to fertilize it more frequently than other potted plants.
If you don’t have the ingredients to make this particular mix for your plant, you can use potting soil and add a layer of pebbles to the bottom of the plant’s pot. The whole goal is to keep the water wet without it sitting in a lot of water.
Anthurium is prone to root rot, so dry feet are as important as the soil mix and fertilizer.
Fertilizer that Anthuriums Need
Anthurium requires fertilizer with nitrogen, phosphorus, and potassium. However, Anthurium likes potassium, so you need to buy a 10-20-30 blend of fertilizer.
Your plants will also need calcium and manganese, so be sure that whatever fertilizer you use also has these ingredients.
You can choose between using a diluted liquid fertilizer, or a time-release type. Unfortunately, it is as easy to overfertilize a plant as to underfertilize one.
Therefore, proceed with caution when adding fertilizer to your Anthurium and give it just a little at a time.
Kind of Pot Ideal for Anthuriums
Anthurium does not like wet feet, so the medium you grow it in should drain well. The pot should have drain holes and not be very much larger than your plant.
Clay pots work best for you if you have a tendency to overwater your Anthuriums. This is because they will absorb any excess water you may apply.
On the other hand, a ceramic pot or plastic pot that holds water longer may be more suitable for those who are less attentive to our plants.
Sunlight Needs of Anthuriums
Anthurium needs indirect sunlight, and they need plenty of it if you want blooms. However, be careful not to place it in direct sunlight as it can burn your plant’s leaves.
The hard part of growing Anthurium is that they need a warm room and require high humidity. Placing your plant either in the kitchen or bathroom helps you meet their humidity needs.
In addition, you will often see Anthurium used to decorate these areas of the home.
The best room temperature for your Anthurium can be as low as 60 degrees Fahrenheit and as high as 75 degrees Fahrenheit. They prefer humidity at around 80 percent, which is higher than most of us keep our homes.
Potted Anthurium can be placed outside, in pots, during the warmer months of the year, and when the nights grow cooler, bring it inside.
Suppose you are lucky enough to live in zone 10 – 12 and plant your Anthurium in your garden. In that case, the only worry you will have is the occasional frost.
Frequently Asked Questions about How to Grow Anthurium
Which variety of Anthurium is most common?
A. Andreanum, aka Laceleaf, or Flamingo Lily, is the most common species of Anthurium. The A. scherzerianum species is a close second, and there are a bunch more (hundreds) you can select from.
Can pests get on my indoor Anthurium?
As with most indoor plants, Anthurium is not immune to pests. Spider mites, thrips, scale, aphids, and mealybugs can attack your plant. If not dealt with, they can weaken your plant, and blooms will be less frequent.
Is Anthurium poisonous?
Since it’s poisonous, you should wear gloves when handling Anthurium and it should be kept away from children and animals. It is only toxic in large amounts, but the plant’s sap can irritate one’s skin.
