Dancing bones cactus (Hatiora salicornioides) is a small, shrubby cactus plant with slender, segmented stems. Also known as drunkard’s dream, bottle cactus, or spice cactus, dancing bones produces deep yellow-orange blooms on the bottle-shaped stem tips in spring.
A native of Brazil, dancing bones cactus isn’t a desert cactus but rather an epiphytic denizen of the rainforest. The stems are spineless, although older plants may develop a few spiny growths at the base. A mature dancing bones cactus plant reaches heights of 30-45 cm
