Overview
The ornamental sweet potato vine is a selected form of the same species as the sweet potato, bred for striking foliage rather than tubers. It grows rapidly, spilling and trailing to fill containers and ground beds with vivid leaf color.
Popular cultivars range from bright chartreuse-lime to deep purple-black and tricolor variegation, with leaf shapes from broad hearts to deeply lobed. It is one of the easiest and most dramatic foliage spillers for summer plantings.

- Flowers: Occasional trumpet-shaped morning-glory-like blooms (rare in cultivation)

Care & growing
Light: Full sun gives the most intense color; tolerates part shade.
Water: Keep consistently moist; vigorous growth means it can be thirsty in containers.
Soil: Rich, well-drained potting mix or garden soil.

Habitat & origin
Ipomoea batatas originated in tropical Central and South America and has been cultivated for thousands of years for its tubers.
The ornamental forms are grown worldwide as warm-season annuals in hanging baskets, containers, and bedding schemes, prized as spiller and ground-cover foliage.
Frequently asked questions
How do I overwinter sweet potato vine?
Take stem cuttings and root them indoors, or dig and store the tubers in a cool, dry place, then replant after the last frost.
Why is my vine taking over the container?
It is naturally vigorous. Pinch or trim it regularly to keep it in bounds and to encourage bushier growth.
How do I get the brightest leaf color?
Grow it in full sun. The chartreuse and dark cultivars develop their richest color with more light.
