Lady's slipper is one of the best container plants for warm climates.
This striking succulent has mostly leafless, lime green stems, about ½
inch in diameter, that stand straight up, or are arched and wavy. This
plant forms a clump of stems to about 2 feet tall by 3 feet wide. In the
fall and spring, unusual orange-red slipper-shaped flowers appear along
the stems. Hummingbirds are attracted to the flowers. Lady's slipper
needs good drainage, and is extremely drought tolerant, requiring only
bi-monthly irrigation, even in containers. In the hot low deserts it
appreciates some filtered shade. It will tolerate full sun, although the
stems can look chlorotic in
extreme exposures. Lady's slipper is quite frost tender, and can
suffer damage at 30° F. In addition to container plantings, it
is ideal for use under desert trees. USDA Zone 10.
