Adenia keramanthus


Adenia keramanthus is a sparingly branched succulent herb/shrub from a tuberous rootstock (pachycaul). It is fast growing and can reach heights of approximately 2 - 3 feet.

It branches freely on the upper third and can bloom at only 6 inches tall. The flower is a cream-colored cup, facing downward, and produces a single seed pod. The flowers are often produced before the leaves are fully developed. Adenia keramanthus' fruits are approximately the size of a chicken egg. The fruits are bright red.

This species is an exception within its genus because the plant's trunk and leaves are covered with fine grey or rusty brown hairs. The general habit is that of a succulent, few-stemmed shrub rather than the vining form of many other species.


As with all Adenias, every part of this plant is toxic. Please handle with caution, particularly when pruning.
