The “String of Elephants” plant, more widely recognized as “String of Dolphins,” is a captivating succulent with unique visual appeal. Its distinctive, dolphin-shaped foliage and cascading growth make it a favored choice for hanging baskets and elevated displays.
Understanding Your String of Elephants
This succulent is scientifically known as Senecio peregrinus (or Curio x peregrinus). It is a hybrid, believed to be a cross between Senecio articulatus (Candle Plant) and Senecio rowleyanus (String of Pearls). Its small, fleshy leaves are curved, mimicking leaping dolphins. These unique leaves grow along trailing stems, which can extend up to three feet.
Essential Care for String of Elephants
Light
The String of Elephants thrives in bright, indirect light, such as near an east or south-facing window with a sheer curtain. At least six hours of daily light helps maintain the distinctive dolphin shape of its leaves. Too much direct, harsh sunlight can scorch the delicate foliage. Insufficient light causes stems to stretch and leaves to lose their unique form, a condition called etiolation.
Watering
This succulent stores water in its plump leaves, so proper watering is key. Use the “soak and dry” method: water thoroughly until drainage occurs, then let the soil dry completely before rewatering.
Overwatering causes root rot and mushy stems. Underwatering leads to shriveled leaves, signaling the plant is drawing on its internal water reserves. Adjust frequency seasonally, reducing it during winter dormancy.
Soil and Potting
A well-draining soil mix prevents waterlogging and root rot for the String of Elephants. A specialized succulent or cactus mix provides necessary drainage and aeration. Incorporating amendments like perlite or pumice can further enhance drainage. Pots with drainage holes are essential for water to escape. Choose a pot size appropriate for the root ball, allowing for some growth without being excessively large, which can hold too much moisture.
Temperature and Humidity
The String of Elephants prefers average household temperatures, ideally 60-80°F (16-27°C). It tolerates typical indoor humidity and does not require special humidification. It is not frost-tolerant and should be protected from freezing temperatures, though it can endure cooler conditions down to 40°F (4°C).
Fertilizing
Fertilize the String of Elephants sparingly, as succulents have low nutrient requirements. During its active growing season (spring and summer), apply a diluted succulent fertilizer once or twice. Avoid fertilizing in fall and winter when the plant is dormant. Over-fertilization can cause nutrient burn and harm the plant.
Propagating String of Elephants
Propagating the String of Elephants is straightforward using stem cuttings. Select a healthy stem and use a clean, sharp knife or scissors to take a cutting with several “dolphin” leaves. Allow the cut end to air dry and form a callus for a few days; this helps prevent rot when planted. Once callused, place the cutting directly onto well-draining succulent soil.
Cuttings can also be rooted in water, though transferring to soil later requires careful acclimation. For soil rooting, bury the cut end slightly, ensuring some leaves remain above the soil line. Keep the soil lightly moist until roots develop, which typically takes a few weeks. Regular pruning for propagation also encourages a bushier parent plant.
Common Problems and Solutions
The String of Elephants can encounter common issues, often related to improper care. Shriveled or deflated leaves usually indicate underwatering; a thorough watering should rehydrate them. Mushy or yellowing stems and leaves often signal overwatering and potential root rot. In such cases, reduce watering frequency and ensure proper drainage.
Insufficient light causes the plant to stretch and its leaves to lose their dolphin shape. Move the plant to a brighter, indirect light location to correct this. Pests such as mealybugs can occasionally affect the plant; these are identified as small, white, cottony masses. Treat affected areas with rubbing alcohol on a cotton swab or insecticidal soap.
