Emerald Palm Zamioculcas zamiifolia

ZZ plant is an erect, semi-evergreen perennial in the Araceae (ariod) family and native to Africa. The species name means with leaves like Zamia, which is an unrelated genus. This plant has a slow growth rate, reaching 2 to 4 feet in height and width.

In the landscape, ZZ plant needs to be planted in partial to deep shade and highly organic or sandy soil with good drainage. It has bulbous fleshy rhizomes that give rise to glossy leaves that store water and make it highly drought tolerant. 

As a houseplant, pot it in well-drained potting 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. Propagate by division or leaf cutting. This plant has a medium toxicity to cats and dogs.

ZZ plant is one of the easiest to grow, low-maintenance houseplants and is seen frequently in commercial interiorscapes. 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.
