Zamioculcas zamiifolia Raven™ 'Dowon'

Raven™ ZZ plant is a tropical succulent houseplant in the Araceae (ariod) family. The species name means with leaves like Zamia, which is an unrelated genus. This plant has a slow growth rate, starting at 6 inches and eventually reaching 3 feet in height and width.

In the landscape Raven ZZ needs partial to deep shade and soil with good drainage. Plant less than 12 inches to 3 feet apart. However, it is best grown as a houseplant potted in well-drained soil that is watered routinely but allowed to dry out between waterings, as wet feet are not tolerated. Water it only once a month in winter months when it goes dormant; water twice monthly in the summer, but only if the soil has dried out completely. Use a balanced fertilizer once or twice a year. This plant can be treated in much the same way as cactus and other succulent plants.  While they will grow in very low levels of light, even in areas with only fluorescent light,  they do best with bright indirect sunlight. Scalding and browning of leaves can occur if the plant is placed in direct sunlight. This plant can be propagated by division, leaf, or stem cutting. This plant has a medium toxicity for humans and animals. Wear clothes when handling.

This cultivar has lime green new growth that turns a dramatic purple-black color as it ages. It stores water in its thick petioles and a tuber-like rhizome, making it an easy to grow houseplant that withstands even dark conditions. 

In some areas, it may be possible to grow this plant in a container outdoors if it is brought in once the temperature falls below 60 degrees F.
