Rhipsalis cereuscula is a shrubby to bushy, epiphytic cactus, up to 3 feet (60 cm) long. It forms small light green stems crowned with clusters of tiny “rice” shaped joints. Erect at first, but becomes pendant as size increases. Excellent for hanging baskets. Flowers are bell shaped, white to pinkish, up to 0.6 inch (1.5 cm) long and up to 0.8 inch (2 cm) in diameter.
