The tropical butterworts hail from south-central Mexico, the center of their diversity. Many are also natives of the Caribbean islands, Central America, and subtropical regions of Florida, with a smattering of species in South America. They come in all shapes and sizes. Some varieties grow as rosettes of broad leaves over half a foot across, while others are barely an inch wide. Some of the rarer ones have long, narrow, upright leaves, which make them look more like sundews than butterworts. Their variety is astounding, linked by the common theme of conspicuous, orchid-like flowers. Each variety, species, and hybrid has its own distinctive flower.
