An attractive South African species from a variable genus that contains diverse plants such as vining, scandent species and thick, succulent, stone-like plants. This species looks as though it may be related to Kalanchoe or similar plants, but for the distinctive bloom, with it they typical red pom-pom bloom of many Senecio species. This species has a tall succulent stem that will form adventitious offsets, with succulent leaves that look like Myrtle leaves, green with a coat of silvery tomentum.

A choice miniature from Mexico that grows in a full compact rosette to about 6 inches. The stiff leaves are very thick and succulent terminating in a sharp spine. With age the plant develops white filaments along the leaf margins, which grow fairly long and curl. This form has bold creamy white variegation along the margins. Cold hardy for gardens to freezing and just below. Small enough and slow enough for pot culture.

A rare variegated form of the species. The caudex is variegated with yellow. 

Not to be confused with Adenium, a completely different genus. Actually succulent forms of the Passifloraceae or Passion Flower family, many Adenias form thick stems which endear them to caudiciform plant lovers. However, when young they little resemble the future finished product. Typical young venenata are tall and resemble an upside-down elongated carrot. The leaves are accompanied by thread-like tendrils which vine around any available object. The caudex thickens with age and can reach 6 feet in very old plants and the vine can go on for 30 feet or more, but can be trimmed to keep it manageable. Leaves are stellate and the flowers are tiny, green and dioecious. Native to central and eastern Africa.
