Description

Lady's slipper is a unique succulent shrub comprised of densely packed lime-green cylindrical stems that can reach 3-4 ft. tall. Attractive orange and yellow slipper-shaped flowers provide accent color on the tops of stems in spring and fall and attract hummingbirds.

Native to the Sonoran Desert of northwestern Mexico and Baja California, Lady's slipper is naturally adapted to heat, aridity and periods of drought. It is a popular accent plant in containers, around rocks and in small planter spaces in southwestern style gardens. It grows best in well-drained soils, with periodic summer water and protection from hot sun exposures. It is adapted to warm and frost-free inland zones in sunny microclimates where winter temperatures stay above 30°F.

Water Needs

Lady's slipper is well adapted to all parts of the Inland Empire in sunny exposures with normal winter rains and low amounts of summer irrigation. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains often provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates Lady's slipper can grow with varying amounts of water; little supplemental water is needed during summer following the flowering cycle.
