The Black ZZ Plant, also known as ‘Supernova’, 'Oscura', or Raven ZZ, is a visually striking and unique cultivar of the Zamioculcas zamiifolia species. What sets this cultivar apart is its striking foliage that starts out bright lime green that eventually hardens to a rich purple-black, creating a contrasting appearance to any collection. Like other ZZs, the Black ZZ is also low light and drought-tolerant.
Medium plants measure between 8–15" tall from the soil line to the top of the foliage
Large plant measures between 18-22" tall from the soil line to the top of the foliage
Arrives in a nursery grow pot nestled in your planter choice
If you purchase a large plant with a planter, the planter will ship separately
Large plants require less frequent waterings due to their higher volume of soil
Care Guide
Black ZZ PlantZanzibar, Kenya, Eastern Africa
Plant Care
Thrives in medium to bright indirect light, but can tolerate low indirect light. Not suited for intense, direct sun.
Water every 2-3 weeks, allowing soil to dry out between waterings. Expect to water more often in brighter light and less often in lower light.
You might spot large potato-like rhizomes under the surface of the ZZ Plant's soil. These store water to help the plant survive drought in its native habitat.
Sad Plant Signs
