String of Spades, also known as Ceropegia woodii ‘Heartless’, is a low-maintenance trailing succulent that combines botanical interest with ornamental beauty. This variety is admired for its unique spade-shaped foliage and elegant cascading habit, offering a fresh twist on the classic heart-leaf form. Its decorative appeal, low-maintenance nature, and suitability for hanging baskets make it a favorite among houseplant enthusiasts. The name highlights its distinctive leaf form while maintaining recognition within the popular String of Hearts family.
Native to Southern Africa, the String of Spades produces slender, trailing stems lined with small, spade-shaped leaves that display shades of green, silver, and sometimes subtle purple tones on the undersides.
The foliage often features delicate marbling, adding texture and visual interest.
It's fine, cascading growth makes it an excellent choice for hanging planters, shelves, and elevated containers.
The String of Spades plant is a compact yet vigorous trailing succulent, with vines that can reach 4 feet long under favorable conditions.
Individual leaves remain small, usually less than an inch in size, while the plant spreads gracefully rather than growing upright, creating a soft, draping effect. The String of Spades flowers are typically pale pink to mauve with darker accents and bloom during spring and summer.
These delicate blooms resemble tiny lanterns and appear sporadically along the stems. While not the primary attraction, the flowers add a subtle ornamental bonus and reflect the plant’s botanical charm.
As a unique variety of String of Hearts, it offers eye-catching foliage, graceful growth, and easy adaptability to indoor spaces. Its distinctive leaf shape, drought tolerance, and cascading habit make it an excellent choice for plant lovers seeking a rare yet approachable statement plant.
When and How to Water Your String of Spades
The String of Spades plant is a drought-tolerant plant that stores water in its tuberous roots and fleshy leaves, allowing it to thrive even when watering is occasionally missed. Overwatering is the most common cause of failure, so allowing the soil to dry fully between waterings is essential. The String of Spades needs infrequent watering, with more moisture during the growing season (March–September), once every 7-14 days, and minimal watering specialized succulent potting soil about every 3-4 weeks during dormancy (October–February).
In spring and summer, during the growing season, water every 7–14 days, using enough water to thoroughly moisten the soil while ensuring excess drains out completely. In warm months, the plant grows actively and benefits from slightly more frequent watering, especially in bright light or warmer indoor environments. However, the soil should always dry out between watering cycles to prevent root rot.
In fall and winter, during the dormant season, water every 3–4 weeks using a light but thorough soak, only after the soil is completely dry. Growth slows significantly in cooler months, and excess moisture can easily lead to rot. Reducing watering during dormancy helps maintain healthy roots and prevents stress on the plant.
Light Requirements – Where to Place Your String of Spades Plant
When growing indoors, place the plant near an east- or south-facing window where it receives 4–6 hours of bright, indirect light per day.
Adequate light ensures compact growth, strong color, and healthy trailing stems. Too little light can cause leggy growth and faded leaf color, while direct midday sun may scorch the foliage.
Supplemental grow lights can help in low-light homes. When growing outdoors, provide bright shade or gentle morning sun for 4–5 hours daily, avoiding harsh afternoon sunlight.
In outdoor conditions, filtered sun under a pergola or tree canopy is ideal, helping maintain vibrant foliage without sunburn.
Optimal Soil & Fertilizer Needs
String of Spades requires a well-drained, airy soil and light NPK fertilization once a year in spring during active growth to maintain healthy roots and steady development. Poor drainage is one of the main causes of root rot, so soil composition plays a critical role in long-term health.
Planet Desert specializes in succulents and has , that includes an organic substrate with mycorrhizae to help with the growth of a healthy root system, to help your succulents thrive.
Use NPK fertilizer in a 5-10-5 ratio once a year in the spring, and refrain from feeding in the fall and winter. Overfertilizing can cause weak, stretched growth, so a light feeding approach is best.
Hardiness Zone & More
In the United States, this is mostly an indoor plant, but if you live in southern Florida or Hawaii, then you can cultivate it outdoors in USDA zones 10-11.
It prefers warm climates with good air circulation and protection from frost.
Outdoors, maintain temperatures above 50°F and avoid prolonged exposure to cold or heavy rain.
Moderate humidity is beneficial, but excessive moisture should be avoided. Bright shade or partial sun works best, especially in hot regions.
Indoor Growing String of Spades Requirements
The trailing String of Spades Plant grows well indoors when provided with bright indirect light, warm temperatures, and good airflow. Ideal indoor temperatures range between 65–80°F, and the plant benefits from occasional rotation to ensure even growth. Keep it away from cold drafts, heaters, or overly humid areas.
Wildlife – String of Spades Flowers Attracts the Following Friendly Pollinators
String of Spades produces small tubular flowers that attract beneficial pollinators such as bees, hummingbirds, and small butterflies. These pollinators help support local ecosystems and add ecological value to outdoor plantings.
Butterflies
Bees
Hummingbirds
Lady Bugs
Multi Pollinators
Other Birds
According to the ASPCA, Ceropegia woodii is considered non-toxic to cats, dogs, and horses, making it a safer choice for pet-friendly homes. However, ingestion of large amounts of plant material may still cause mild digestive upset.
How to Propagate Your String of Spades Plant
String of Spades is easy to propagate using stem cuttings, tubers, or layering methods, making it ideal for sharing or expanding collections. Stem cuttings should be taken during spring or summer, allowed to callus for 24 hours, and then placed in moist, well-draining soil. Keep cuttings in bright indirect light and lightly moist conditions until roots develop.
Another effective method is layering, where trailing stems are pinned onto the soil while still attached to the mother plant. Once roots form, the new plant can be separated and grown independently.
Key Takeaways
- String of Spades is a drought-tolerant trailing succulent ideal for low-maintenance plant lovers.
- It thrives in bright indirect light and performs well in both indoor and warm outdoor settings.
- Its pet-safe nature makes it a great choice for homes with cats and dogs.
