Dieffenbachia amoena 'Tropic Snow' is one of the largest dieffenbachia plants. The canes sport large, oblong green leaves that are variegated with white or cream. This robust plant can grow up to 2 m though houseplants average about 1.3 m in height.
Dieffenbachia is a genus of tropical flowering plants in the family Araceae. It is native to the New World Tropics from Mexico and the West Indies south to Argentina. Some species are widely cultivated as ornamental plants, especially as houseplants, and have become naturalized on a few tropical islands. Dieffenbachia is a perennial herbaceous plant with straight stem, simple and alternate leaves containing white spots and flecks, making it attractive as indoor foliage. Species in this genus are popular as houseplants because of their tolerance of shade.
