sweet potato vine is the trailing stem of the Ipomoea batatas (sweet potato) plant, used for ornamental, edible and agricultural purposes.

What Is Sweet Potato Vine?

Sweet potato vine is the above-ground growing part of the sweet potato plant, available in both edible commercial varieties and ornamental varieties bred for colorful foliage. It is a warm-season plant native to tropical regions of the Americas.

In practice, we manage over 12,000 acres of commercial sweet potato fields annually, so we work with sweet potato vine every growing season. It is far more versatile than most people realize, beyond just supporting root growth.

Q: Is sweet potato vine the same as regular potato vine?

A: No, they are completely different plants. Sweet potato vine comes from the Ipomoea batatas species, while regular potato vine comes from the Solanum tuberosum species. Regular potato vine and its fruit are toxic to humans, while most sweet potato vine varieties are non-toxic.

Q: Can you eat sweet potato vine?

A: Yes, the leaves and young stems of edible sweet potato vine varieties are safe to eat. 2026 nutritional research confirms they are packed with fiber, vitamins, and minerals, and have been used as a leafy green in many cuisines for centuries.

How to Grow Sweet Potato Vine At Home

Growing sweet potato vine at home is simple and low-maintenance, even for beginner gardeners. You can grow it indoors as a houseplant or outdoors in gardens or containers. Follow these 4 easy steps to get started:

1. Source a fresh, firm sweet potato root from a grocery store or local nursery. Avoid soft or sprouted roots that show signs of rot.
2. Place the sweet potato halfway in a glass of clean room-temperature water, with the wider end submerged. Put the glass near a window with 6+ hours of indirect sunlight.
3. Change the water every 2 days to prevent rot. Once vines reach 4-6 inches in length, you can cut them and root separately, or transplant the whole sprouted potato into soil.
4. Transplant into well-draining potting soil, water 2-3 times per week, and fertilize once every 2 weeks for full, lush growth.

Common Uses of Sweet Potato Vine

Sweet potato vine has three main categories of uses, depending on whether it is an edible or ornamental variety.

Ornamental Landscaping & Decor

Ornamental sweet potato vine is bred for vibrant purple, green, or variegated foliage, and it grows very quickly. In practice, it is one of the most popular trailing plants for hanging baskets, ground cover, and border edging. It tolerates hot, dry summer conditions better than most ornamental foliage plants, which makes it a favorite for warm climate gardens.

Agricultural & Culinary Uses

For commercial sweet potato farming, healthy sweet potato vine cuttings are used to plant new crops each season. The leaves and young stems are used as a leafy green vegetable in many Asian, African, and Caribbean cuisines. Industry consensus is that sweet potato vine also works well as a cover crop to prevent soil erosion and suppress weed growth between main crop plantings.
