Disocactus alatus

Disocactus alatus (=Pseudorhipsalis alata) is an epiphytic hanging cactus native to Jamaica. The pendulous, flattened stems will reach up to 16 feet (3-4 m) in length and 1-2 inches (2.5-5 cm) wide. They are very fast growers and make an attractive basket plant.

Blooming Time: The small 5/8-inch (1.5 cm) flowers are formed along the edge of the stems. The number of blooms makes it very showy.

Culture: Disocactus alatus need partial shade to full shade with a moist well-drained soil mix. In the greenhouse, we use a soil mix consisting of 3 parts peat moss to 1 part coarse sand, with small bark chips added to increase drainage. During the growing season, the plants are kept moist and fertilized on a weekly basis. Since they are vigorous growers, they will outgrow most baskets within a year's time and should be repotted on a yearly basis. During the winter months, the plants are grown on the dry side and temperatures are dropped to 50°F (10°C).

Propagation: Disocactus alatus are propagated from cuttings or division of older plants or by seed.

Disocactus alatus was featured as Plant of the Week October 3-9, 2003.
