Rhipsalis is a genus of the Cactaceae of over 60 South
American species, mostly of epiphytic cacti. Some species
are commonly found in tropical Africa, Madagascar and Sri
Lanka, but it is probable that they have been introduced.
The genus name comes from the Greek for 'wicker', in
reference to the flexible branches of some species. Many
have hanging stems, sometimes over 6 feet long. In nature
they are hanging from trees, climbing up them, and
sometimes sprawling over rocks. The genus Rhipsalis is
being cultivated as a potted plant.
The stems are tube-like or flat and leaf-like, and most
of the time carry aerial roots. They have small,
occasionally fairly long-lasting flowers which can be
followed by decorative berrylike fruits. The flowers
appear in the stems, opening only at night.
Hardiness zones 11, (4°C/40°F). They like shade and
some humidity, but in general, will take temperature
close to freezing for short periods. The soil mixture
should be rich in organic matter and draining well.
Rhipsalis usually like warm climates, high humidity,
shade or a position which receives morning sun. A daily
spray of water will be appreciated by most of the species
that like a high humidity.
