Ornamental Features

Proven Accents® Blackie Sweet Potato Vine is primarily valued in the garden for its spreading and trailing habit of growth. Its attractive deeply cut heart-shaped leaves remain deep purple in color with hints of black throughout the season.

Landscape Attributes

Proven Accents® Blackie Sweet Potato Vine is a dense herbaceous annual with a trailing habit of growth, eventually spilling over the edges of hanging baskets and containers. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance plant. The flowers of this plant may actually detract from its ornamental features, so they can be removed as they appear. It has no significant negative characteristics.

Proven Accents® Blackie Sweet Potato Vine is recommended for the following landscape applications;

  • Border Edging
  • General Garden Use
  • Groundcover
  • Container Planting
  • Hanging Baskets

Planting & Growing

Proven Accents® Blackie Sweet Potato Vine will grow to be about 10 inches tall at maturity, with a spread of 6 feet. Its foliage tends to remain low and dense right to the ground. This fast-growing annual will normally live for one full growing season, needing replacement the following year.

This plant does best in full sun to partial shade. You may want to keep it away from hot, dry locations that receive direct afternoon sun or which get reflected sunlight, such as against the south side of a white wall. It does best in average to evenly moist conditions, but will not tolerate standing water. This plant should not require much in the way of fertilizing once established, although it may appreciate a shot of general-purpose fertilizer from time to time early in the growing season. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Proven Accents® Blackie Sweet Potato Vine is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. Because of its trailing habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
