ZZ plant better known as zamioculcas zamiifolia. It comes from Tanzania, Zanzibar. Sounds pretty elegant, doesn't it? We were walking through the local Home Depot a few weeks ago and there were ZZ plants. Not knowing anything about them and not too happy with the price, we moved on to things we knew would grow in the new shade garden. On the way to check out, my husband found a zz plant leaf lying on the ground so placed it in our cart. We decided to put it in the garden and see if it would do anything. I frankly thought it would brown out and die but it hasn't. It keeps sitting there. The leaves remain green and supple, which makes me question how it propogates. According to the University of Connecticut extension service, a leaflet can fall to the ground and produce bulblets. Ah hah! Maybe it's producing bulblets and we just haven't seen anything yet. I'll let you know. Happy Florida Gardening.
