String of Hearts Green (Ceropegia Woodii)
The classic String of Hearts (Ceropegia woodii) is a timeless staple in the indoor gardening world and an absolute must-have for trailing plant lovers. Native to the rocky ledges of South Africa, Swaziland, and Zimbabwe, this incredibly elegant semi-succulent produces long, wire-thin, purple vines adorned with perfectly heart-shaped leaves. What makes the classic green variety so stunning is its deep, rich emerald foliage that is heavily marbled with a striking, metallic silver lacing. Flip a leaf over, and you are greeted by a gorgeous, muted amethyst-purple underside.
Though it looks like a delicate beaded curtain, the String of Hearts is a survivor. It stores water efficiently in its thick, fleshy leaves and in small, potato-like tubers (bulbils) that form along the vines and in the soil. It boasts an impressively fast, cascading growth habit that can trail downwards for several feet, making it the ultimate centerpiece for a hanging basket, a macrame hanger, or draped elegantly off a tall bookshelf.
Light
▾
Bright, indirect light is best. While it can handle a bit more shade than its variegated cousin, it still needs plenty of bright ambient light to keep the spaces between the leaves short and compact. A few hours of gentle morning sun will bring out the deep purple color on the undersides of the leaves. Avoid harsh, blazing afternoon sun, which can scorch the foliage.
Watering
▾
Treat this plant like a cactus or succulent. Allow the potting mix to dry out 100% from top to bottom between waterings. When you do water, soak it thoroughly until water drains out the bottom. Bottom-watering is an excellent method to ensure the delicate vines resting on the top soil do not stay overly wet, which can cause stem rot.
Humidity
▾
It prefers a dry, arid environment and thrives in normal household humidity. Do not mist the leaves! Misting provides absolutely no benefit to this succulent vine and increases the risk of fungal infections and rot where the dense leaves meet the soil.
Growing Media
▾
It requires a highly aerated, fast-draining, gritty soil mix. Use a premium cactus and succulent mix, and amend it heavily with coarse perlite or pumice (a 50/50 ratio works great). The roots are fine and shallow, so ensure the pot has excellent drainage to prevent the underground tubers from rotting.
Feeding
▾
They are very light feeders. Use a balanced, water-soluble fertilizer or a specialized succulent fertilizer diluted to half-strength just once a month during the active growing season (spring and summer). Stop fertilizing completely during the winter.
Bald on Top / Thinning at the Crown
▾
This happens when the top of the pot is in the shadows. The plant needs light hitting the soil surface to push out new growth. Lower the plant or adjust its position so the crown gets light. Loop a few long vines back into the pot and pin them to the soil to fill it out quickly.
Mushy, Yellowing Leaves at the Base
▾
This is a classic sign of overwatering and root rot. The delicate vines resting on wet, heavy soil will quickly rot away. Immediately stop watering, allow the plant to dry out completely, and ensure your soil mix is gritty enough. You may need to snip the healthy vines and re-root them if the base is entirely dead.
Leaves Spaced Very Far Apart (Leggy Growth)
▾
This is called etiolation. The plant is stretching in search of light, causing the distance between the heart-shaped leaves to become very long and sparse. Move the plant to a significantly brighter location to encourage dense, compact growth.
