String of Dolphins (Senecio peregrinus): The Playful Succulent That Leaps into Hearts
Few plants capture imagination like the String of Dolphins. With leaves shaped like tiny leaping dolphins, this trailing succulent blends charm, novelty, and easy care in one graceful package. Officially known as Senecio peregrinus, it is a hybrid between Senecio rowleyanus (String of Pearls) and Senecio articulatus (Candle Plant). The result? A plant that’s both whimsical and hardy, perfect for hanging baskets, shelves, or sunny windowsills.
This guide dives deep into everything you need to know about String of Dolphins. From its unique appearance and growth habits to detailed care tips, propagation methods, and creative ways to display it, you’ll see why this plant has become a favorite among succulent lovers.
What Makes String of Dolphins Special?
The magic is in the leaves. Each tiny leaf resembles a miniature dolphin mid-leap, complete with a curved “body” and a tiny “fin.” As the plant matures, it forms long trailing vines covered with dozens of these playful shapes, creating the look of a pod of dolphins swimming through air.
The plant’s flowers are another surprise. In late fall or winter, mature String of Dolphins can produce small, white blooms with a cinnamon-like scent. While the flowers are delicate, the plant is primarily grown for its foliage and trailing form.
Growth Habit and Size
String of Dolphins is a trailing succulent that grows quickly under the right conditions. Vines can reach up to two feet long, making it ideal for hanging baskets or cascading from shelves. The plant’s compact leaves store water, which allows it to tolerate periods of dryness better than many other houseplants.
Unlike its parent, String of Pearls, the dolphins are slightly thicker and more sculptural, giving the plant a more pronounced texture and playful silhouette.
Ideal Growing Conditions
Light Requirements
String of Dolphins thrives in bright, indirect light. A south- or west-facing window is ideal, where it can enjoy several hours of filtered sun. Too little light causes the “dolphin” shapes to stretch and lose definition, while too much direct sun can scorch the leaves.
If natural light is limited, grow lights can supplement. Aim for 10–12 hours of light daily to maintain healthy growth and compact leaves.
Temperature and Humidity
This succulent prefers temperatures between 60–75°F. It tolerates typical household humidity well but dislikes overly damp conditions. Keep it away from drafts, heaters, or cold windows during winter.
Soil Needs
A fast-draining succulent or cactus mix is best. Adding perlite or coarse sand improves drainage and prevents root rot. Avoid heavy soils that retain water, as these can lead to problems.
Watering the Right Way
The key to success with String of Dolphins is careful watering. Like most succulents, it prefers the “soak and dry” method:
- Water thoroughly until water drains from the pot’s bottom.
- Allow the soil to dry completely before watering again.
- In winter, reduce watering frequency as the plant’s growth slows.
Overwatering is the most common cause of problems, leading to mushy leaves and root rot. When in doubt, it’s safer to underwater than overwater.
Fertilizing for Healthy Growth
Feed String of Dolphins lightly during its active growing season (spring and summer). A diluted succulent fertilizer every 4–6 weeks provides enough nutrients to support healthy foliage and trailing vines. Stop feeding in fall and winter when the plant is dormant.
Pruning and Shaping
Regular pruning helps maintain a full, attractive shape. Trim back leggy or damaged vines to encourage branching and denser growth. Pruned cuttings can be rooted to create new plants, making this succulent both decorative and generous.
Propagation: Multiply Your Dolphins
String of Dolphins is easy to propagate, which makes sharing with friends fun. The two main methods are:
Stem Cuttings
- Cut a healthy vine with several dolphin leaves.
- Let the cutting dry for a day to callus.
- Place it on moist succulent mix, ensuring nodes touch the soil.
- Roots develop in a few weeks; mist lightly during this time.
Water Propagation
- Place cuttings in a jar of water with only the nodes submerged.
- Change water weekly and transfer to soil once roots are 1–2 inches long.
Potting and Repotting
String of Dolphins prefers to be slightly root-bound and does not need frequent repotting. Refresh the soil every 2–3 years or when the plant outgrows its pot. Choose a shallow container with good drainage holes to prevent water buildup.
Common Problems and Solutions
Shriveling Leaves
- Cause: Underwatering or overwatering.
- Solution: Check soil moisture; water deeply if dry or allow to dry if wet.
Leaves Losing Dolphin Shape
- Cause: Insufficient light.
- Solution: Move to a brighter location or supplement with grow lights.
Root Rot
- Cause: Poor drainage or overwatering.
- Solution: Repot in fresh, well-draining soil and trim away damaged roots.
Seasonal Care
- Spring/Summer: Active growth. Water regularly, fertilize lightly, and provide bright light.
- Fall/Winter: Dormant period. Reduce watering and avoid fertilizing. Keep in a cooler spot (50–60°F) to encourage blooming.
Pairing and Display Ideas
String of Dolphins is a natural showpiece in hanging baskets, allowing its trailing vines to drape gracefully. It also pairs beautifully with other trailing succulents like String of Pearls, String of Bananas, or String of Hearts for a playful mixed arrangement.
For a whimsical display, combine it with sea-themed décor — shells, driftwood, or ceramic fish — to enhance the plant’s ocean-inspired look.
