Bloom Time: Spring and summer
Disocactus flagelliformis is a cactus with thick hanging stems, each with 8 – 13 ribs, up to 3.3 feet (1 m) long, and up to 0.75 inches (1.9 cm) in diameter. The needle groups are tiny, almost fuzzy-looking, and have 15 – 20 fine reddish-yellow spines each. Flowers are beautiful, curved, bright pink in color, up to 3 inches (7.5 cm) long and up to 1.5 inches (3.8 cm) in diameter, produced along the stems in spring and summer. The fruit is red, globose, bristly, and up to 0.5 inches (12 mm) long.
How to Grow and Care
Disocactus flagelliformis is easy to cultivate and a relatively fast-growing cactus. Their trailing stems make these cacti ideal plants for a hanging basket. Line the basket with sphagnum moss before filling it with potting mix and make sure it is hung where the prickly stems will not pose a treat to the unwary. If Disocactus flagelliformis is grown in a pot, hang the pot up or attache it to a high shelf. If it is left free-standing, it can soon be overbalanced by the lengthening stems.
To propagate, use either 6 inches (15 cm) tip or 6 inches (15 cm) segment of any part of the stem. Allow each cutting or segment to dry for three days; then insert it about 0.8 inches (2 cm) deep in a small pan or pot of the recommended potting mixture for mature plants; be sure that any stem segment is planted with the bottom end down.
