Dümmen Orange Black Heart Sweet Potato Vine (Ipomoea batatas ‘Black Heart’)

Dümmen Orange Black Heart Sweet Potato Vine (Ipomoea batatas ‘Black Heart’) is a dramatic foliage plant prized for its nearly black heart-shaped leaves and vigorous trailing habit. This striking ornamental sweet potato vine adds bold colour, texture, and contrast to containers, hanging baskets, window boxes, and landscape plantings throughout the growing season.

The large, glossy leaves emerge in deep shades of burgundy-purple and mature to rich purple-black, creating a stunning backdrop for flowering annuals and other foliage plants. The dark foliage provides exceptional contrast when paired with chartreuse, silver, pink, white, yellow, and red companion plants, making it a favourite choice for professional container designs and seasonal displays.

Black Heart develops a vigorous trailing habit that quickly cascades over container edges and spreads through landscape beds. Its rapid growth and bold foliage create instant impact, while its heat tolerance and adaptability ensure reliable performance throughout the summer months. Whether used as a spiller in mixed planters or as a colourful groundcover accent, it delivers season-long interest with minimal maintenance.

In Alberta, Black Heart Sweet Potato Vine performs exceptionally well as a summer annual, providing lush foliage and dramatic colour from planting time until frost.
