Overview

Summary, origin & habitat
A creeping succulent native to dry parts of South Africa, where it trails beneath shrubs and rocks and roots where stems touch the ground. It is grown mainly in hanging baskets.
Interesting facts
The plant naturally creeps along the ground rather than hanging; hanging baskets display the same stems in a vertical direction.
Name story
Curio means curiosity, reflecting the unusual form. Rowleyanus honors British succulent specialist Gordon Douglas Rowley.
History & legends
The bead-like foliage inspired the common names string of pearls, rosary vine and necklace plant. It has become a classic novelty succulent.

Care

Light
Bright indirect light with gentle morning sun; light should reach the top of the pot as well as the trailing stems.
Temperature
70–80°F (21–27°C) in summer; 50–60°F (10–16°C) in winter is acceptable if kept drier.
Watering
Water when soil is nearly dry and pearls begin to feel slightly soft.
Fertilizing
Monthly at ½ strength during spring–summer, or feed lightly once in spring and once in early summer.

Safety

Toxic if eaten?
Yes
Who is affected
People, cats and dogs
Possible effects
May cause nausea, vomiting, lethargy or skin irritation; larger amounts may be more serious.

A safety guide, not medical or veterinary advice. “Non-toxic” does not mean edible — even non-toxic plants can cause stomach upset. For a person, contact Poison Control; for a pet, a veterinarian.

Tips

Pruning
Remove dead or sparse vines and shorten healthy stems to encourage branching. Lay trimmed stems on the soil surface to root.
Propagation
Stem cuttings or layering are fast and reliable. Bury or pin several nodes against the mix.
Repotting
Repot every 2–3 years in spring using a shallow, well-drained container. Older plants are often renewed from cuttings.

Ecology

Adaptation strategy
Nearly spherical leaves minimize exposed surface area and reduce water loss. A translucent epidermal window lets light enter the interior photosynthetic tissue.
Ecological application
Suitable for xeric hanging containers and frost-free groundcover. Outdoor flowers can support small pollinators, but the plant is toxic if eaten.
