Curio rowleyanus, commonly known as String-of-Pearls, is a perennial succulent vine native to the arid regions of southwest Africa, specifically the Cape Provinces of South Africa. It is well-adapted to dry, rocky slopes and scrublands where it spreads across the ground or hangs from rocky outcrops. This plant is characterized by its unique, spherical leaves that resemble a string of pearls, hence its common name. The leaves are an adaptation to store water, allowing the plant to thrive in its native arid environment. String-of-Pearls can reach lengths of up to 3 feet (90 cm) when grown in cultivation. It produces small, white, brush-like flowers with bright-colored stamens that emit a cinnamon-like fragrance, typically blooming in the summer. The flowers are not particularly showy but are interesting upon close inspection.

In cultivation, String-of-Pearls is valued for its distinctive foliage and is often used in hanging baskets or as a trailing plant in indoor settings. It requires minimal maintenance, making it a popular choice for gardeners. It prefers well-draining soil, infrequent watering to mimic its native arid conditions, and a few hours of direct sunlight or bright, indirect light. Overwatering is a common issue that can lead to root rot. It is also sensitive to cold temperatures and should be protected from frost. While it is not known for being invasive, it can become pot-bound, so periodic repotting may be necessary to maintain plant health.CC BY-SA 4.0
