Etymology

Origin of epiphyte

First recorded in 1840–50; epi- + -phyte

Explanation

When one plant grows on another without harming it, it's an epiphyte. Tiny ferns and mosses growing on tree trunks are epiphytes. In rainforests, orchids and bromeliads are common epiphytes, attached to other plants but getting their nutrients from the air around them. In more temperate regions, you might see lichens (not technically plants, but still epiphytes) and moss growing on dead trees and guess they're responsible for killing their host — but these epiphytes are simply taking advantage of the increased sunlight and physical support of the bare trunks. You can grow an epiphyte of your own, too, by buying a tiny "air plant."
