The oval-shaped leaves are actually leaf-like cladodes, which are 0.8–2 cm long and 0.1-0.2 cm wide, and arise in groups of four or more from the stem. Occurring in spring, the small white or pinkish-white flowers are 0.3-0.5 cm long and arise in clusters off the stem. Flowers are followed in summer by small round berries 0.5 cm in diameter, which bear a black 3 mm diameter seed. Initially green, the berries mature and turn red in the winter. The root system is a mat of fibrous roots with bulbous tubers, from which plants may resprout.
