Growing ZZ houseplants is easy and especially suited for the forgetful gardener.This virtually indestructible houseplant can take months and months of neglect and low light and still look amazing.ZZ plant stems grow in a graceful, wand-like shape that starts thick and bulbous at the base and then tapers to a point. Along the stem are fleshy, oval-shaped leaves that make the plant look like stylized feathers. The entire plant has a waxy, shiny coating that makes it appear to resemble those made of plastic.
