Senecio rowleyanus, commonly known as the String of Pearls, is one of the most enchanting and recognisable trailing succulents, prized for its cascading vines of perfectly round, bead-like leaves. A member of the Asteraceae family and native to the dry, rocky regions of South Africa, its a plant that combines sculptural beauty with low-maintenance ease.
Each slender stem carries rows of small, spherical green pearls modified leaves that store water and give the plant its distinctive necklace-like appearance. When grown in bright, indirect light, the vines can trail gracefully over 1 metre, creating a flowing curtain of greenery. In summer, mature plants produce clusters of tiny, white, cinnamon-scented flowers that add an extra layer of charm.
Elegant, playful, and minimalist, Senecio rowleyanus is a timeless favourite for contemporary interiors, hanging planters, or sunny windowsills where its unique form can be fully appreciated.
Senecio rowleyanus Care Guide
Light
Thrives in bright, indirect light and can tolerate several hours of gentle morning or late afternoon sun. Too little light will cause sparse, elongated growth, while harsh midday sun may scorch the delicate pearls. A bright south- or west-facing window with filtered light is ideal.
Watering
Allow the soil to dry out completely between waterings. String of Pearls stores moisture in its leaves, so its best to underwater rather than overwater. During spring and summer, water thoroughly, then let the soil dry fully before watering again. In autumn and winter, water sparingly about once every 34 weeks. Always ensure excellent drainage and avoid letting the plant sit in water.
Temperature and Humidity
Temperature: Prefers warmth between 1826 C. Protect from cold drafts and avoid temperatures below 10 C.
Humidity: Average indoor humidity is sufficient. Avoid overly humid conditions, which can lead to rot.
Soil and Potting
Use a fast-draining cactus or succulent mix ideally with added perlite, pumice, or coarse sand to prevent water retention. A shallow pot with drainage holes works best. Repot every 23 years in spring to refresh the soil and prune back leggy growth if necessary.
Feeding
Feed monthly during spring and summer with a diluted cactus or succulent fertiliser. Over-fertilising can cause weak, leggy growth. Suspend feeding during autumn and winter.
Pruning and Maintenance
Trim long or sparse vines to maintain a fuller shape. Pruned cuttings can easily be propagated simply place them on top of moist cactus soil, where they will root along the stem. Wipe leaves gently to remove dust and preserve their natural shine.
Growth and Maturity
A moderately fast grower, Senecio rowleyanus can reach over 1 metre in trailing length under ideal conditions. With age, it forms dense, cascading curtains of pearls that flow beautifully from hanging baskets or high shelves.
Common Issues
-
Shrivelled pearls: Underwatering or excessive heat.
-
Mushy stems: Overwatering or poor drainage.
-
Sparse growth: Insufficient light.
-
Pests: Occasionally affected by mealybugs or aphids treat with neem oil or insecticidal soap.
Background and Benefits
Native to the arid regions of South Africa, Senecio rowleyanus is adapted to extreme drought conditions, storing water efficiently in its plump leaves. Its trailing form allows it to sprawl along rocky slopes or hang from cliffs in the wild an adaptation that also makes it ideal for hanging planters indoors.
This plant symbolises renewal and endurance, reflecting its ability to thrive in minimal conditions. Non-toxic to touch but mildly toxic if ingested, it should be kept out of reach of pets and small children.

Styling Tip
Senecio rowleyanus looks stunning in hanging baskets, macram planters, or tall pots where its pearl-like vines can cascade freely. For a striking, textural display, pair it with contrasting succulents such as Sedum burrito (Burros Tail) or Crassula ovata (Jade Plant). It also complements modern, minimalist interiors with its geometric charm and sculptural silhouette. Place near a bright window or shelf edge for a living, green waterfall effect that brings natural movement and elegance to any space.
