The String of Dolphins (Senecio peregrinus) is a charming and unique succulent known for its trailing vines with leaves shaped like tiny jumping dolphins. Treat it as you would any drought-tolerant, water-storing plant: plenty of light, restrained watering, sharp drainage.
Light
Bright, indirect light for at least six hours a day — near a south- or west-facing window is ideal. Harsh direct sun can scorch the leaves, so filter intense summer light with a sheer curtain.
Watering
Use the soak-and-dry method: water thoroughly, let the excess drain away, and allow the soil to dry out completely before watering again. Cut right back in winter while the plant is dormant. Yellowing, mushy leaves are the sign of overwatering — the one mistake this plant won't forgive.
Soil
A free-draining cactus or succulent mix, improved with perlite or coarse grit if in doubt. The pot must have a drainage hole.
Temperature and humidity
Happiest at 18–24°C and fine slightly cooler, but keep it above 10°C. Average indoor humidity is perfect — no misting required.
Feeding
A diluted succulent fertiliser once a month through spring and summer. Don't feed in autumn or winter.
Pruning and propagation
Trim leggy or tired vines to keep the plant compact — and don't waste the cuttings. Let a healthy cutting callous for a day or two, plant it in well-draining soil, keep it barely moist, and it will root into a new plant.
Good to know
Watch for mealybugs and spider mites; treat promptly with neem oil or insecticidal soap. Rotate the pot occasionally so the vines grow evenly. And keep it out of reach of pets — like most senecios, it's mildly irritating if ingested.
