Zamioculcas Black Raven is not a fussy plant. ZZ plants are known for their wide tolerance of differing light and water conditions and their low-maintenance care. What makes this plant so special is his dark-hued leaves which range from green to violet-purple black. As his leaves form they start a bright green and gradually over about 2 months turn darker and darker. Zamioculcas Black Raven is a good looking plant and that explains why he is considered "rare" or hard to get. Rare or not we love having him around. By Plantsome.
