Curio rowleyanus – Succulent Elegance with a Trailing Twist


Curio rowleyanus, better known as string-of-pearls, is a distinctive trailing succulent that brings sculptural flair to any plant collection. Its cascading stems are lined with nearly spherical leaves, each functioning as a miniature water reservoir. Originally described as Senecio rowleyanus, it was reassigned to the genus Curio by Paul V. Heath in 1999. One of its most remarkable features is a translucent window on each leaf — a clever desert adaptation that lets light reach internal photosynthetic tissues while minimizing surface area and water loss.

Where Curio rowleyanus Comes From

Curio rowleyanus – Care Instructions for Indoors

Light: Prefers bright, indirect light. Some morning sun is fine; protect from strong midday rays
Water: Allow soil to dry out completely between waterings. Never let roots sit in water
Soil: Use a sharply draining mix, e.g., cactus soil with perlite or pumice
Humidity: Normal room humidity is sufficient — no misting required
Temperature: Keep between 21–26 °C. Avoid cold drafts or temperatures below 10 °C
Feeding: Fertilize once a month during active growth with a diluted succulent fertilizer
Repotting: Every 2–3 years to refresh soil and check root health
Propagation: Simple: place stem cuttings on moist substrate — roots form at leaf nodes
Pruning: Trim tangled or leggy strands to shape and stimulate new growth
Support: Trail from shelves, or use basket clips to train growth where needed


Potential Problems and How to Fix Them

Mealybugs & Aphids: Wipe with neem oil or treat with insecticidal soap
Spider mites: Less common, but increase humidity slightly and wipe leaves if needed
Root Rot: Caused by poor drainage or overwatering — always use pots with drainage holes
Shriveled Pearls: Often a sign of underwatering. Adjust frequency accordingly
Yellowing Leaves: Linked to overwatering — let soil dry thoroughly
Leggy Stems: Usually from insufficient light. Move to a brighter location to support fuller growth
Fungal Spots: Caused by stagnant air or overwatering. Improve airflow and avoid wetting foliage


How to Keep Your String-of-Pearls Thriving

Location: South- or east-facing window with filtered light is ideal
Watering Style: Bottom-watering works well to prevent rot
Don’t Mist: This is a dry-climate succulent — excess humidity can cause fungus
Use a Grow Light: Helpful in darker months to maintain healthy stems
