Zamioculcas zamiifolia, affectionately called the ZZ plant or Zanzibar Gem, is a tropical plant in the aroid family, Araceae. It is native to Zanzibar, Kenya, and Eastern Africa. You might spot large potato-like rhizomes under the surface of its potting mix. Having evolved in drier conditions than most other aroids, these plants have evolved rhizomes that store water to help the ZZ plant survive drought in its natural environment. The rhizomes are actually underground stems, and what you see above ground are the stems' leaves. Using these underground rhizomes, the plant slowly creeps over time to new locations, spawning new aboveground leaves along the way.
Tolerates low light, but prefers medium to bright indirect light. Not suited for intense, direct sun.
Watering frequency depends largely on lighting conditions. Bright light requires more frequent watering; low light less frequent watering. Allow to dry out completely between waterings.
Don’t sweat it. Average home humidity is fine; can tolerate dry air.
Temperatures of 60°F-85°F. Average home temperature is suitable.
While growth is slow, the ZZ can reach 16”- 28”.
Essentially, none. Just don’t overwater.
Poisonous if ingested.
Best practice is always to keep houseplants out of reach of small children and pets.
