Araceae (Colocasia)

When we hear about the family Araceae, we can get confused because this is not the most common name for the family.

Very decorative, these beauties are popular as houseplants for their beautiful leaves and (sometimes) flowers.

rhizomatous or tuberous. The leaves can be totally different from plant to plant. The special physical detail of these green beauties is that the inflorescence consists of a spadix, which is surrounded by a modified leaf called a bract. Apart from the physical detail, the superpower of this family is incredible: some of them can produce heat! Their flowers can reach up to 45°C, even when the temperature around them is completely different. The reason for this ability is to attract insects to pollinate the plants. Amorphophallus paeoniifolius (elephant foot yam) is one of the plants that produces heat.

Propagating Colocasia is more complicated than other plants. You can’t propagate Colocasia from cuttings. As they grow from a bulb, you will have to dig up the parent plant, preferably in fall, and divide the new tubers from the original plant. Repot the new plant in a large pot with drainage holes and fill it with potting soil (cutting soil).
