String of Bananas makes a great hanging plant, with its cascading vines and glossy, banana-shaped leaves creating a flowing curtain of greenery. Native to South Africa, this fast growing succulent, formerly known as Senecio radicans and now classified as Curio radicans, adds texture and movement whether spilling from a hanging basket, trailing off a shelf, or softening the edge of a garden wall. 

The String of Bananas plant typically grows up to 3 feet long and 12 inches wide when grown in hanging containers, although the stems can extend longer in favorable outdoor conditions.

The vines are densely packed with glossy, green, banana-shaped leaves arranged in a semi-spiraled pattern.

These leaves are not only attractive but also serve a functional role by storing water during dry periods.

From late winter to early spring, the tiny, star-shaped white or pale pink flowers may release a light cinnamon or clove-like scent.

Flowering is more common outdoors or when grown in bright light and slightly cooler winter conditions.

Thanks to its durability and unique appearance, String of Bananas is popular in modern container arrangements, xeriscapes, vertical gardens, and minimalist interior designs.  It’s worth noting that String of Bananas is often confused with “String of Fishhooks”, which is a slightly bluish-gray cultivar with thinner, longer leaves. 

When and How to Water Your String of Bananas Plant 

The drought-tolerant String of Bananas prefers to be watered every 7-10 days when the soil is completely dry in the spring and summer, and every 3-4 weeks or less in the fall and winter. Like most succulents, it stores water in its stems and leaves, making it more resilient to dry conditions than many houseplants. Overwatering is a common issue, so it’s always better to underwater than overdo it. 

From spring to early fall, during the active growing season, water deeply but infrequently, typically every 7-10 days. Wait until the top 2-3 inches of soil are dry before watering again. Always ensure the pot has drainage holes to prevent root rot. 

From late fall to winter, in the dormant season, you may only need to water once every 3–4 weeks. It’s best to err on the dry side when in doubt. In the winter, they are dormant, and if they receive too much water, they may quickly develop root rot. 

Light Requirements – Where to Place Your Curio radicans 

String of Bananas thrives in bright light, needing 4–6 hours of sunlight daily indoors and up to 6 hours of morning or filtered sun outdoors.

Whether grown indoors or outside, avoid placing your plant in full, deep shade; insufficient light causes stretched growth and a loss of the rich green color.

Rotate potted plants regularly to ensure even exposure and balanced trailing. 

When grown indoors, place your String of Bananas near a south- or west-facing window where it can receive plenty of indirect light for at least 4-6 hours a day.

It can tolerate some direct sun, especially in the morning, but harsh midday rays through glass can scorch the leaves.

If your indoor space has lower light, consider supplementing with a grow light to prevent leggy or pale growth. 

For outdoor growth, this Senecio plant flourishes in bright, filtered sunlight or partial shade, particularly in hot climates. Aim for about 4 to 6 hours of early morning sun, followed by indirect light or dappled shade in the afternoon. If you're in a coastal or mild zone, it can take more sun, but in desert or high-heat regions, afternoon shade is best to prevent sunburn. 

Optimal Soil & Fertilizer Needs 

Use a fast-draining cactus or succulent mix, and feed lightly once a year in the spring during the active season. The ideal soil for String of Bananas is a gritty, well-aerated mix that allows excess moisture to drain quickly. Planet Desert specializes in succulents and has specialized succulent potting soil, opens in a new tab that includes an organic substrate with mycorrhizae to help with the growth of a healthy root system, to help your succulents thrive. Remember, good drainage is essential to prevent root rot, especially in hanging containers or shallow pots. 

In the spring, during the growing season, fertilize once a year with a diluted liquid NPK fertilizer or a balanced formula like 5-10-5 at half strength. This helps encourage vigorous trailing growth and overall plant health. Avoid over-fertilizing, as it can lead to weak stems and overly rapid growth that becomes leggy. 

Do not fertilize during the fall and winter when the plant enters dormancy. Its nutrient needs decrease significantly, and any excess fertilizer may harm the roots or cause salt buildup in the soil. 

Hardiness Zones & More 

The String of Bananas thrives indoors in 60-80°F with low humidity and bright light, and outdoors in USDA Zones 9-11 with frost protection.
