Abstract
The new cultivar of Dieffenbachia amoena originated as a mutation of the Tropic Snow cultivar U.S. Plant. Pat. No. 2,869). The new cultivar can be readily distinguished from its parent cultivar by the exhibition of a compact erect growth habit and a greater quantity of irregular greenish-yellow markings on the leaves. The leaf blades of the new cultivar tend to be more coriaceous and more undulated, and the upper surface of the leaves is more glossy. Additionally, the lower leaves of the new cultivar tend to remain fresh considerably longer and tend to be retained on the plant substantially longer than those of the parent cultivar. A highly attractive foliage plant is provided for use as an ornamental house plant.
