Landscape Attributes

Sweet Caroline Sweetheart Lime™ 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 medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

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.

Sweet Caroline Sweetheart Lime™ Sweet Potato Vine is recommended for the following landscape applications;

• Mass Planting
• General Garden Use
• Groundcover
• Container Planting
• Hanging Baskets

Planting & Growing

Sweet Caroline Sweetheart Lime™ Sweet Potato Vine will grow to be about 12 inches tall at maturity, with a spread of 3 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 12 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. This fast-growing annual will normally live for one full growing season, needing replacement the following year.

This plant does best in a location that gets morning sunlight but is shaded from the hot afternoon sun, although it will also grow in partial shade. 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. It may require supplemental watering during periods of drought or extended heat. 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.

Sweet Caroline Sweetheart Lime™ 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.
