Overview
String of Dolphins is a trailing succulent famous for its whimsical leaves, each shaped like a little dolphin mid-leap. It is a hybrid (Curio x peregrinus, formerly Senecio) between String of Pearls and the candle plant.
The dolphin shape comes from small notch-like wings on each plump, curved leaf. Like its parents, it stores water in its succulent foliage and trails gracefully, making it a sought-after novelty for bright windowsills and hanging pots.
How to identify it
Look for trailing stems lined with small, curved, leaping-dolphin-shaped leaves.
- Leaves: plump, curved, blue-green, with two small side wings creating the 'dolphin' silhouette
- Habit: trailing, slender stems hanging down
- Flowers: small, white, puffball-like blooms with a light cinnamon scent
- Size: trails up to about 2-3 ft
- Note: dolphin shape is most pronounced on healthy, well-lit plants
Care & growing
Light: Bright indirect light with some gentle direct sun keeps the dolphin shape crisp.
Water: Let the soil dry out fully between waterings; these succulents rot easily if overwatered.
Soil: Gritty, fast-draining succulent or cactus mix.
Temperature: 65-80F; protect from frost.
Feeding: Light feeding once or twice in the growing season.
Propagation: Easy from stem cuttings laid on or pinned to moist succulent mix; let cuttings callus first.
Habitat & origin
As a cultivated hybrid, String of Dolphins does not occur in the wild. Its parent species originate from arid regions of southern Africa.
It is grown worldwide as a novelty houseplant, prized for hanging baskets and bright windowsills where its trailing stems can be displayed.
Frequently asked questions
Why do my leaves look like plain ovals, not dolphins?
Insufficient light flattens the shape. Give it bright light with a bit of direct sun to bring out the characteristic dolphin curve.
How often should I water it?
Only when the soil is completely dry, often every 1-2 weeks in summer and far less in winter. Overwatering is the most common cause of failure.
Why are the stems shriveling?
Shriveled, soft leaves can mean either underwatering (dry, deflated) or overwatering/rot (mushy). Check the soil and roots to tell which, then adjust.
