The Enchanting String of Dolphins: A Complete Care Guide for Your Unique Succulent

Houseplants have always been a popular choice for enhancing indoor spaces, offering both aesthetic appeal and health benefits. Among the myriad of indoor plants, the String of Dolphins stands out with its distinctive foliage and easy-care nature. True to its name, this succulent’s leaves resemble tiny leaping dolphins, making it a charming and whimsical addition to any plant collection. If you’re considering adding this captivating plant to your home, here’s a comprehensive guide to ensure it thrives under your care.

Understanding the String of Dolphins

Unique Dolphin-Shaped Leaves

The String of Dolphins, scientifically known as Senecio peregrinus, is part of the Asteraceae family. What sets this succulent apart is its remarkable foliage. The leaves are shaped like miniature dolphins, leaping joyfully along its trailing vines. This unusual shape not only makes it a conversation starter but also a delightful piece of living decor.

Trailing Vines

This plant grows in long, trailing vines, making it an excellent choice for hanging baskets or high shelves where its cascades can be fully appreciated. With proper care, the vines can reach impressive lengths of 2 to 3 feet, creating a lush, green waterfall effect.

Ideal Growing Conditions

Light Requirements

To keep your String of Dolphins healthy and vibrant, provide it with bright, indirect light. Direct sunlight can scorch its delicate leaves, while too little light can cause the plant to become leggy, with sparse foliage. A spot near a north or east-facing window, where it can receive plenty of bright yet filtered light, is ideal.

Watering Needs

One of the key aspects of caring for any succulent, including the String of Dolphins, is proper watering. This plant stores water in its leaves, meaning it requires infrequent watering. Over-watering can lead to root rot, a common issue with succulents. Allow the soil to dry out completely between waterings. Depending on your home’s humidity and temperature, this might mean watering every two to three weeks.

Soil Preferences

Well-draining soil is crucial for the String of Dolphins. Use a cactus or succulent mix that allows excess water to escape quickly, preventing the roots from sitting in damp conditions. You can enhance drainage further by adding perlite or coarse sand to the soil mix.

Temperature and Humidity

While the String of Dolphins thrives in typical household temperatures, it is not frost-tolerant and should be kept indoors during cold seasons. This is particularly important in regions like Stokes County and Winston-Salem, NC, where winters can be quite cold. Additionally, this succulent appreciates higher humidity levels and good airflow. Regularly ventilate the room and consider using a humidifier if the air is particularly dry.

Flowering and Fragrance

One of the delightful surprises of growing a String of Dolphins is its flowering period. In late fall and early winter, the plant produces small, white flowers that emit a cinnamon-like fragrance. These blooms add another layer of charm to this already captivating plant.

Pet-Friendly and Non-Toxic

For pet owners, the String of Dolphins is a particularly appealing choice. Unlike many houseplants that can be toxic to pets, this succulent is non-toxic and safe for both cats and dogs. This makes it an excellent option for households with curious pets who might be tempted to nibble on the greenery.

Seasonal Care Tips

Spring and Summer

During the growing season in spring and summer, your String of Dolphins will appreciate regular watering and feeding. Use a balanced, water-soluble fertilizer diluted to half strength once a month to support its growth. Ensure the plant receives ample light and monitor for any signs of pests like aphids or mealybugs.

Fall and Winter

As the plant enters its dormant period in the fall and winter, reduce watering frequency. This is also when the plant may begin to flower, filling your home with its subtle, cinnamon scent. Avoid fertilizing during this time and ensure the plant remains in a warm, draft-free location indoors.

Common Issues and Solutions

Leggy Growth

If your String of Dolphins starts to look leggy, with long, sparse stems and fewer leaves, it’s likely not receiving enough light. Move it to a brighter location and consider supplementing with a grow light if natural light is insufficient.

Root Rot

Over-watering is the primary cause of root rot in succulents. Ensure your plant is in well-draining soil and that the pot has drainage holes. If you notice any signs of rot, such as blackened stems or mushy roots, cut back on watering immediately and let the soil dry out completely.


While relatively resistant to pests, the String of Dolphins can occasionally attract aphids, mealybugs, or spider mites. Regularly inspect your plant, especially the undersides of leaves and along the stems. If you spot any pests, treat them with insecticidal soap or neem oil.

Propagation Tips

One of the joys of growing succulents is their ease of propagation, and the String of Dolphins is no exception. To propagate, take cuttings of healthy vines and allow them to callous over for a day or two. Then, place the cuttings in well-draining soil and water sparingly until roots develop. This is a wonderful way to expand your collection or share the plant with friends and family.

Styling and Display Ideas

The String of Dolphins’ trailing nature makes it a versatile plant for various display options. Here are a few ideas to showcase its beauty:

  • Hanging Baskets: Place the plant in a decorative hanging basket to let its vines cascade freely, creating a stunning visual effect.
  • High Shelves: Use the plant on a high shelf where the vines can drape down, adding a touch of greenery to upper spaces.
  • Mixed Arrangements: Combine the String of Dolphins with other succulents or houseplants in a mixed arrangement for a diverse and attractive display.
  • Terrariums: Incorporate it into an open terrarium design, where its unique leaves can be viewed up close and personal.

Final Thoughts

The String of Dolphins is more than just a houseplant; it’s a piece of living art that brings whimsy and charm to any space. With its dolphin-shaped leaves, easy-care requirements, and pet-friendly nature, it’s an excellent choice for both novice and experienced plant enthusiasts. By providing the right conditions and a bit of TLC, you’ll be rewarded with a lush, trailing plant that captures the imagination and enlivens your home.

So, if you’re looking to add a touch of the extraordinary to your indoor garden, consider the String of Dolphins. This enchanting succulent is sure to make a splash, delighting you with its playful foliage and delicate blooms year-round.
