What Is String of Pearls?

The string of pearls plant, formally known as Curio rowleyanus, was discovered by German botanist Herman Jacobsen in 1968. Its unique appearance features plump water storage vessels in the shape of pearl-like leaves that grow on slender and delicate stems. These leaves have a distinct dark green line that aids in efficient photosynthesis.

Native to South Africa, the string of pearls thrives in arid environments by creeping horizontally, forming a thick green ground cover. When cultivated indoors, this plant prefers bright indirect sunlight and is often showcased in hanging containers to display its trailing vines.

Propagation Methods

From a Leaf:

1. Choose a plump, unblemished leaf.

4. Plant the leaf in a cactus and succulent potting medium.
5. Keep the medium lightly moist and provide bright indirect sunlight for new growth.

From a Stem Cutting:

1. Cut a four-inch stem from the growing end of a tendril.
