Bloom Time: Mid-spring
Disocactus phyllanthoides is an easy-to-grow jungle cactus with green or reddish stems that grow to 3.3 feet (1 m) long or more. The primary branching stems are woody at the base, flattened at the apex, up to 16 inches (40 cm) long, and up to 0.2 inches (0.6 cm) thick. The secondary stems are flat, lanceolate, acute with coarsely scalloped margins, toothed, up to 12 inches (30 cm) long, and up to 2 inches (5 cm) wide. Flowers are funnel-shaped, pink, up to 4 inches (10 cm) long, and up to 3.5 inches (9 cm) in diameter. Fruits are ellipsoid, up to 1.6 inches (4 cm) long, with low ribs, green at first, and later red.
How to Grow and Care
Disocactus should be grown in rich but still well-draining soil. They should be watered regularly and fertilized as well. This is essential for good growth and flowering. Keep relatively dry in winter or when night temperatures remain below 10° C. Disocactus dislike extreme heat and cold, so they are best green-housed during the depth of winter and heat of summer in hot, dry climates such as mine. They also prefer shade to sun and a little extra humidity in the air. Flowering in spring and summer, the flower color varies from white, yellow, red, or purple, depending on the species.
Disocactus can be reproduced both by seeds and cuttings.
