Sweet Potato Vine

The Story

Plant Bio

Ipomoea batatas, the sweet potato, is a trailing and twining warm-season vine from Mexico, grown both for its edible tuberous roots and, in ornamental forms, for its foliage. Heart-shaped or deeply lobed leaves up to six inches long come in green, chartreuse, bronze and near-black, and pink funnel-shaped flowers appear sparingly in warm summers.

The ornamental foliage cultivars sold for containers are the same species as the crop, and their roots are edible — NCSU notes only that they are less tasty. In the ground the vines run six to ten feet, so a plant that trails neatly from a basket will cover a large area of bed if planted out.

Uses & Benefits:

Bold heart-shaped or lobed foliage in chartreuse, bronze and near-black, spilling from containers all summer.

A productive root crop for warm summers, and the leaves and stems are edible as greens.

Pollinators visit the sparse flowers, including specialist bees associated with the morning glory family.

How to Grow

Plant slips or rooted cuttings after all frost has passed.
Give it full sun and loose, free-draining soil.
Allow six to ten feet of run, or grow it in a container.
Water regularly; it tolerates both dry and wet spells.
Avoid heavy nitrogen, which gives leaves at the roots' expense.
Lift the roots before the first frost and cure them warm.

Pro Tip

Cure lifted roots at about 85F for a week before storing — uncured sweet potatoes taste starchy and rot far sooner.

Common Questions

Sweet Potato Vine questions

What zones can Sweet Potato Vine grow in?

Sweet Potato Vine is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Sweet Potato Vine deer resistant?

Not reliably. Deer may browse Sweet Potato Vine, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does Sweet Potato Vine bloom?

Sweet Potato Vine typically blooms in summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Sweet Potato Vine need full sun?

Sweet Potato Vine does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Sweet Potato Vine drought tolerant?

Yes — once established (usually after the first full season), Sweet Potato Vine handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
