Identification and care

Opposite, thick, waxy leaves grow on flexible vines. Give bright filtered light and a support or hanging space. Water thoroughly when the upper mix has dried, then drain. Do not keep roots continuously wet.

Standard soil mix

Use two parts fine orchid bark, one part potting mix, and one part perlite. Choose a snug pot with an open drainage hole.

Flowering and propagation

Star-shaped flowers form rounded clusters on persistent spurs. Do not remove old spurs; they can bloom again. Root stem cuttings containing at least one node.

A climbing or epiphytic habit explains the need for air around the roots, filtered canopy light, and support for vines.
