Genus of about 500 species of often epiphytic, evergreen shrubs, root climbers, or small trees from variable habitats, usually rainforest, in Florida, Mexico, the West Indies, and Central and tropical South America. There are two basic types of Philodendron. The first group, the climbers, are well suited to the average room, as long as you provide firm support for the stems. A feature of many climbing Philodendrons is the production of aerial roots from the stems, and these roots have an important part to play. Push them into the compost to provide moisture for the upper leaves. Flowers and fruits rarely appear under home conditions. Most of the second group, the non-climbers, are capable of growing into immence plants with large, deeply-lobed leaves. All parts may cause mild stomach upset if ingested, and contact with the sap may irritate skin.
