ZZ is a rhizome plant having its origin in drought-prone areas of Africa. It has thick waxy green leaves of an oval shape that makes it look like stylized feathers. The branches grow in an elegant way of wand-like shape that starts thick and rounded at the bottom and then tapers to a point. The plant gives a real joy to grow and to have displayed within a home and offices around the world. ZZ usually grows slowly to a height and width of 2-3 feet. Don't do overwatering. If it is getting too much water, the leaves will turn yellow and its underground rhizomes may rot.
