For some odd reason a lot of people are typing some form of the question "can Anthurium be grown in water" into search engines. I receive email all the time asking this odd question. As a result, I've been attempting to learn where this notion may have originated. I believe it is from one of three sources. One seller of plants advertised, at least for a while, the species from Peru Anthurium regale should be grown in water. I believe they have since revised their ad. The Anthurium craze has hit southeast Asia with a vengeance and many growers there are trying to learn how to best grow the species. It appears someone has started advising they should be grown in water. And of course, you can buy Anthurium hybrids on eBay attached to volcanic rock and the rock should be kept sitting in water according to the sellers. The notion Anthurium regale "should" be grown in water came from a misunderstanding of how noted grower Mardy Darian was growing his Anthurium regale seeds. I have spoken to Dr. Darian at least four different times. The good doctor starts his seeds in high quality sphagnum moss and places the moss in a pot which is then placed in about 1/2 inch of water. The moss acts as a "wick" and draws the water up to the seeds. When the plant develops it is not in water, it is in damp moss! As a result, the plants grow very well.... for a while. However, almost every grower who has bought one of these plants after it leaves Dr. Darian has later learned to keep the plant healthy they must place it in a very loose soil which drains quickly. The plant will not survive well in super wet conditions. The volcanic rock idea has also lead people to believe Anthurium species can be grown in water. They can't! There is no such thing as an aquatic Anthurium. They do love damp, humid conditions, but they don't grow in water. I have confirmed this with noted botanist Dr. Tom Croat of the Missouri Botanical Garden in St. Louis. Dr. Croat is recognized as the world authority on Anthurium species. What is happening with the volcanic rock is the rock itself is capable of holding water. When you sit the rock in shallow water, with the Anthurium attached on the top of the rock, the rock acts as a wick and draws water from the water basin up to the roots. The roots then draw water from the inside of the rock just as they do in nature while attached to a tree. Many orchid growers use the same technique and for some years crushed volcanic rock was the craze as a "perfect" orchid media. But if you sit the entire rock with the roots in water the plant will eventually die. In nature, the majority of Anthurium species are epiphytic and are attached to a tree limb well up in the rain forest canopy. Most do not even grow in soil, although the majority will grow in soil. Some species do grow in the soil, but they are the minority. Most Anthurium species capture their moisture from the frequent rain in the tropical rain forest and draw some from the high humidity of the forest. (see the photo attached of an Anthurium growing in the canopy). This plant is easily 40 feet (13 meters) off the ground. You can see the root system is simply hanging from the branch. There is no soil. The red berries in the photo are the berries containing seeds of the specimen. Normally, there are two seeds per berry. Birds eat the berries then leave their droppings on other tree branches. Those bird droppings contain just the right amount of moisture and nutrients to cause the seed to germinate and grow another Anthurium on another tree branch. But Anthurium species do not live in water! These are no aquatic species. And by the way, for some reason, many who search for information on Anthurium species are spelling it "anthirium" with an "i" instead of a "u". The correct spelling is I have it at the top of this page. Here's some slightly more detailed information on how Anthurium species grow and reproduce in the wild. This information was prepared with the help of several of the world's best known aroid experts: http://www.exoticrainforest.com/Grow or Growing Anthurium species.html Promise, if you are determined to try to grow an Anthurium in water you will, in time, kill the plant!
