The String of Dolphins (Senecio peregrinus) is a delightful and quirky houseplant, famous for its trailing vines adorned with plump, dolphin-shaped leaves that seem to leap from the stem. This unique succulent is popular among beginners thanks to its resilience, easy care requirements, and charming appearance that brightens up any living space—perfect even for low-light apartments and busy owners.
Light Requirements
String of Dolphins thrives in bright, indirect sunlight—think near an east or west-facing window, but out of harsh direct rays to prevent leaf burn. It can tolerate a few hours of weaker winter sun, but avoid placing it in dark corners or right on scorching windowsills. If using artificial lights, aim for at least 6 hours of light daily.
Watering Schedule
Water String of Dolphins deeply but infrequently—let the top half of the soil dry before watering again. Typically, that means every 2–3 weeks, but always check the soil moisture first. Signs of overwatering include mushy yellow leaves; when it’s underwatered, leaves wrinkle. No humidifier needed, as it tolerates average indoor humidity.
Humidity & Temperature
This plant prefers average home temperatures of 65–75°F (18–24°C). Keep it away from cold drafts, heaters, or air conditioners, as it’s sensitive to sudden temperature shifts and frost. Average room humidity is fine—no special requirements needed.
Soil & Potting
Choose a well-draining succulent or cactus mix. A regular potting mix can work if you add perlite or sand. Repot every 2–3 years, or when roots start crowding, to refresh soil and keep your String of Dolphins healthy.
Fertilizing
Fertilize String of Dolphins lightly—use a diluted, balanced fertilizer once in spring and again in summer. Avoid feeding during fall or winter, as growth slows and extra nutrients aren’t needed.
Common Problems & Solutions
Yellowing and dropping leaves often point to overwatering, while shriveled, brown leaves mean it’s too dry. Watch for pests like mealybugs or spider mites—wipe leaves with a damp cloth to treat. Rotting stems? Re-pot in dry, well-draining soil and adjust your watering habits.
Extra Tips
To showcase your String of Dolphins, let it trail from hanging baskets or high shelves. Pair it with String of Pearls or String of Hearts for a whimsical plant display. Fun fact: these “dolphins” are actually swollen leaves designed to retain water—perfect for busy plant parents!
