Culture
Winter hardy to USDA Zones 9-10. Plants are best grown in medium moisture, well drained soils in part shade to full shade. Plants perform well in a variety of shaded conditions including morning sun with afternoon shade or in bright indirect light. Plants should be regularly watered, but allow the soils to dry between applications. Avoid wet soils. Propagate by leaf cuttings or division. Bring plant indoors in fall when temperatures begin to dip below 60 degrees F.
Noteworthy Characteristics
Zamioculcas zamiifolia, commonly called ZZ plant or aroid palm, is an aroid family member that is native to dry grassland and forest in Eastern Africa. It is a stemless evergreen plant that typically grows to 3’ tall with attractive, pinnately compound leaves rising up from its rhizomes. Each leaf has 6-8 pairs of elliptic, glossy green leaflets (to 6” long). Flowers appear on mature plants. Flower structure consists of a spadix (erect spike of numerous tiny creamy white flowers) encased by a sheath-like green spathe.
Genus name comes from the unrelated genus Zamia and calcas the Arabic name for an elephant's ear (Colocasia sp.).
