ZZ Plant Black Queen will entertain the low light window with its arching stems of waxy green to black leaves. The juvenile leaves start out green and turn black with time. This easy grower requires little light, water and fertilizer to maintain its beauty. Mature plants will reach 2-3 tall and only need bright light, not direct sunlight, and fertilizer once a month. Black Queen is a dramatic houseplant that commands attention in those low light spaces.
