Description. Rhodocactus is a beautiful evergreen... cactus. The stems are thin, branching, and become woody at the base with age. The leaves are succulent, fleshy, lanceolate or oblong-oval, green. The leaf nodes contain long, sharp, straight spines. The buds appear at the tops of the shoots, very large and bright - pink, white, yellow or scarlet, up to 5 cm in diameter, often single. Each flower, unfortunately, remains open for only 2 days, but the faded flowers are immediately replaced by new buds. After flowering, attractive yellow, red or green fruits are formed.
