Zamioculcas  Zanzibar Gem's scientific name, Zamioculcas zamiifolia, gives a hint of its resemblance to the palm-like cycads called zamias.  Tips for caring for Zanzibar Gem: Choose a brightly lit indoor spot with no direct sunlight. Or, in frost-free gardens, grow Zanzibar Gem outdoors in semi shade. Water occasionally, but allow the plant to dry out well between watering. Water less frequently in winter and when the plant is growing in low light.
