Zamioculcas is a monotypic genus of flowering plants in the family Araceae, comprising a single species, Zamioculcas zamiifolia. The genus is a tropical herbaceous perennial native to eastern Africa, where it grows across Kenya, Malawi, Mozambique, Tanzania, Zimbabwe, and the KwaZulu-Natal region of South Africa.
The plant is distinguished by its arching stems bearing glossy, pinnate leaves whose leaflets strongly resemble those of the cycad genus Zamia — a resemblance that gave the genus its name. As a member of Araceae, it contains cyanogenic glycosides and calcium oxalates, compounds characteristic of the family.
Zamioculcas zamiifolia was first described as Caladium zamiifolium by Conrad Loddiges in 1829 and was subsequently placed in the new monotypic genus Zamioculcas by Adolf Engler in 1905. Today it is among the most widely cultivated houseplants in the world, valued for its attractive foliage and tolerance of low light and infrequent watering. Dutch nurseries began large-scale commercial propagation around 1996, driving its spread into the global horticultural trade. Common names include ZZ plant, Zanzibar gem, zuzu plant, emerald palm, and eternity plant. It is winter-hardy in USDA Zones 9 and 10.
Etymology
The genus name Zamioculcas reflects two botanical relationships: the resemblance of its foliage to the cycad genus Zamia, and its membership in Araceae alongside the genus Colocasia, whose name derives from the word culcas or colcas — an ancient Middle Eastern term for taro (Arabic qolqas, Egyptian Arabic: قلقاس). The species epithet zamiifolia means "leaves like Zamia," combining that genus name with the Latin folium (leaf).
Distribution
Zamioculcas zamiifolia is native to eastern and southern Africa, occurring in Kenya, Malawi, Mozambique, Tanzania, Zimbabwe, and the KwaZulu-Natal province of South Africa. In South Africa its national conservation status is Least Concern (LC).
Ecology
In its native range the species has documented ethnobotanical uses: leaf juice is applied to treat earache in Malawi's Mulanje District and Tanzania's East Usambara mountains, bruised plant material is used as a poultice for the inflammatory condition known locally as "mshipa" in Tanzania, and roots are applied to treat ulceration by the Sukuma people of north-western Tanzania.
Cultivation
Dutch nurseries began wide-scale commercial propagation of Zamioculcas zamiifolia around 1996, establishing it as a major houseplant commodity. It is prized for tolerating low light, infrequent watering, and general neglect, making it suitable for indoor environments. The plant is winter-hardy in USDA Zones 9 and 10.
Taxonomy Notes
Zamioculcas zamiifolia was originally described as Caladium zamiifolium by Conrad Loddiges in 1829. Adolf Engler transferred it to the new monotypic genus Zamioculcas in 1905, giving it its current accepted name Zamioculcas zamiifolia (G.Lodd.) Engl. The genus is accepted in GBIF within the family Araceae, kingdom Plantae, with one accepted descendant.
