A Philodendron Selloum or Tree Philodendron is native to South America, but also grows outdoors on the East and Gulf coasts of the United States. Indoors, the easy-care, self-heading Philodendron Selloum takes up a lot of space.
Tree Philodendron often spread 5ft. or more with 2ft.-3ft. leaves. The dark green, shiny leaves are large and deeply lobed. A Selloum does grow a trunk as it matures, but the huge drooping leaves usually hide it. These plants are considered poisonous and should be kept away from pets and children. It takes about 15-20 years for a mature Philodendron Selloum to flower; and it rarely flowers indoors. The pedal-less flowers of a Philodendron Selloum are enclosed in a spathe, a modified leaf, which is often mistaken for the flower itself.
