The ruby necklace plant is native to the Eastern Cape of South Africa where it grows as a low, creeping mat of foliage along the dry, rocky coastal scrublands. It has become popular for growing as a potted plant indoors, particularly in a hanging basket.
The plump, succulent leaves of ruby necklace take on a purple-red tint when exposed to stressful conditions such as exposure to direct hot sun, drought or cold. Ruby necklace plants may produce yellow flowers periodically throughout the growing season, from spring through fall. The blooms close under cloudy conditions and reopen with the sunshine. You also may find ruby necklace marketed with the common name of little pickles or string of pickles. The botanical name Crassothonna capensis is a synonym.
The ideal location is somewhere the foliage can be allowed to cascade, such as in a hanging basket, on a shelf or on a plant stand. The perfect plant for a sunny windowsill. Can be placed outdoors in warm months and grown in the ground in frost-free regions.
