A unique succulent with round bead-like leaves strung together. Looks like a pearl necklace when hung.
About
Curio rowleyanus (formerly Senecio rowleyanus), the string-of-pearls, is a succulent perennial in the family Asteraceae, native to South Africa. Its trailing stems carry small, spherical, bead-like leaves — an evolutionary adaptation that reduces surface area to minimise water loss in arid conditions. It prefers bright light but should be kept slightly away from intense direct sunlight to prevent scorching. As a succulent, it follows a 'dry then water' regime: allow the soil to dry completely before watering again. Overwatering, particularly in hot humid summers, leads to rapid stem rot. Trailing stems extend 30–100 cm, making it ideally displayed in hanging baskets or trailing from shelves. Its pearl necklace appearance makes it one of the most distinctive and fashionable houseplants available.

Growing Tips
Light & Placement
Likes bright light, but direct sun causes leaf burn. A bright spot set slightly back from the window is ideal.
Watering
Water only after the soil has dried completely. Like other succulents it prefers dry-side care, and overwatering leads to rot.
Temperature & Overwintering
Grows at 5-30°C and tolerates fairly cool conditions, but never frost. In winter keep it at a bright indoor window.
Soil & Repotting
Use a free-draining succulent mix. The strands reach 30-100 cm, so a hanging pot or one on a high shelf suits it.
Pests & Cautions
Hot, humid summers cause rot from stagnant moisture. Improve airflow and avoid letting water sit on the leaves.
