String of Pearls (Curio rowleyanus)
Curio rowleyanus
Cascading trailing succulent with pendulous strings of spherical, pearl-like bead foliage.
About This Botanical
A mesmerizing statement trailing plant, Curio rowleyanus (syn. Senecio rowleyanus), commonly known as String of Pearls, forms cascading emerald bead curtains consisting of spherical succulent leaves threaded along slender, trailing stems.
Each bead features a translucent epidermal 'window' that allows sunlight to penetrate deep into the leaf. Thriving in hanging planters, plant stands, and sunny shelves, String of Pearls requires bright light reaching the top crown and careful, infrequent watering.
Botanical Care Essentials
- ☀️ Light: Bright indirect light with morning direct sunlight; ensure crown receives light.
- 💧 Watering: Bottom water or soak only when beads narrow and feel slightly soft/shriveled.
- 🌱 Soil: Gritty, fast-draining cactus and succulent mix with perlite or pumice.
- 🐾 Pet Safety: Toxic to dogs and cats (ASPCA listed). Display in elevated hanging planters.
⚡ Quick Facts
At a Glance- • Light: Bright indirect sunlight with direct morning sun; top of pot must receive light.
- • Water: Bottom soak only when pearls become slightly puckered or soft.
- • Mature size: Trailing vines cascading 2–3+ feet in length.
- • Pet safety: Toxic to dogs and cats (ASPCA listed: pyrrolizidine alkaloids).
- • Beginner-friendly: Intermediate — sensitive to overwatering and crown dampness.
“Why is my String of Pearls dying or turning mushy at the crown?”
Mushy stems at the soil line are caused by overwatering or top-watering where water sits on pearls. Bottom watering in a fast-draining gritty mix under bright light prevents stem rot.
