Growth Stages

1

Transplant Establishment

7-14 days

Young vine with small heart-shaped leaves emerging; stems are thin and tender

Keep soil consistently moist but not waterlogged. Provide bright light indoors or filtered sunlight if transplanting early. Harden off gradually before outdoor planting. Pinch tips after 2-3 sets of leaves to encourage branching.

2

Vegetative Growth

4-8 weeks

Rapid vine elongation with increasing leaf production; leaves develop characteristic lobing and deep purple-black color intensifies with sun exposure

Water regularly as vines grow vigorously. Apply balanced fertilizer every 2-3 weeks or use slow-release fertilizer at planting. Support trailing growth with stakes or allow to cascade. Trim excessive growth if needed.

3

Full Maturity

Maintains through growing season

Fully developed trailing vines 3-5+ feet long with dense, deeply lobed foliage in rich purple-black; occasional small purple trumpet flowers may appear in summer

Maintain regular watering during dry periods. Continue monthly feeding to support vigorous foliage. Prune or pinch back if growth becomes unruly. Monitor for pests in heat and humidity.

4

Fall Decline (Cool Climates)

Variable; begins when temps drop below 60°F

Vines slow growth as temperatures drop; foliage may yellow or fade; frost will kill tender plant tissue

Enjoy the vine through fall. Reduce watering as growth slows. In frost-prone areas, dig tubers before first frost if you wish to store and replant next year. Otherwise, compost the plant.

Uses

🏠

Container and Hanging Basket Ornament

Household

Trailing Sweet Potato Vine 'Ace of Spades' is an exceptional choice for hanging baskets, window boxes, and mixed container plantings, where its deep purple-black foliage creates dramatic visual impact and cascades beautifully. The vigorous growth quickly fills spaces and pairs striking color with minimal maintenance. [source]

🏠

Ground Cover and Landscape Design

Household

In warm climates, 'Ace of Spades' serves as a fast-growing annual ground cover or fill plant, quickly covering bare areas with striking dark foliage that contrasts beautifully with lighter-colored plants and landscape features. Its spreading habit makes it useful for erosion control on slopes. [source]

🍳

Tuber Production

Culinary

While primarily ornamental, the tubers of sweet potato vines are edible and nutritious, rich in vitamins A and C, fiber, and potassium. They can be roasted, boiled, baked, or fried when harvested and cured in fall. [source]

🦋

Pollinator and Insect Habitat

Wildlife

The occasional purple trumpet flowers produced by sweet potato vines attract pollinators including bees and butterflies, while the dense foliage provides shelter for beneficial insects and small creatures in the garden. [source]

🎨

Foliage for Arrangements

Craft

The uniquely lobed, deep purple foliage can be cut for fresh tropical-style arrangements, providing interesting texture and color that lasts well in water when cut stems are properly conditioned. [source]

Harvest Tips

Sweet potato vines are grown primarily for ornamental foliage, not harvested. The tubers may be dug in fall (90-120 days after planting) if you wish to store them for next season or culinary use. Harvest before frost in cool climates. Cure tubers in warm, humid conditions (80-85°F, 85-90% humidity) for 10-14 days before storage in cool (55-60°F), humid conditions.

Fun Facts

  • 🌱 'Ace of Spades' gets its name from the deeply cut, spade-like shape of its leaves, which creates a striking geometric pattern of dark purple-black with lighter veining that becomes more pronounced with full sun exposure.
  • 🌱 Sweet potato vines are technically a different plant from regular sweet potatoes grown for food production (though same species) and are not typically selected for tuber quality; ornamental varieties are bred primarily for dramatic foliage rather than edible root production.
  • 🌱 The vines can grow 3-5 feet or more in a single season in warm climates, making them one of the fastest-growing ornamental vines for containers and can quickly cascade from a hanging basket to create an impressive summer display.
