Species of Dracaena have a secondary thickening meristem in their trunk, which is quite different from the thickening meristem found in dicotyledonous plants and is termed Dracaenoid thickening by some authors. This characteristic is shared with members of the Agavoideae and Xanthorrhoeoideae among other members of the Asparagales. D. americana, D. arborea, D. cinnabari, D. draco, D. ombet, and D. tamaranae are commonly known as dragon trees and grow in arid semi-desert areas. They are tree-sized with stout trunks and stiff, broad-based leaves. The remaining species are known collectively as shrubby dracaenas. They are smaller and shrub-like, with slender stems and flexible strap-shaped leaves, and grow as understorey plants in rainforests. Dracaena plants are suitable for use as houseplants, being a top performer in NASA& x27;s clean air study and tolerant to sparse watering.
