They can be divided into two groups based on their growth habits:
A group of tree-size species with stout trunks and stiff, broad-based leaves, growing in arid semi-desert areas, and known as dragon trees.

A group of smaller, shrubby species with slender stems and flexible strap-shaped leaves, growing as understorey plants in rainforests (and very popular as houseplants), and known collectively as shrubby dracaenas. Many of the species common as houseplants are toxic to pets, though not humans, according to the ASPCA among others.
