Sweet Caroline Upside™ Key Lime Ornamental Sweet Potato Vine

Bright key lime foliage with sharply cut, maple-like leaves and subtle purple veining.

Sweet Caroline Upside™ Key Lime is an ornamental sweet potato vine grown for foliage, producing vigorous climbing growth that also trails, adding height, structure, and bright contrast to containers and landscapes.

What You'll Use It For

A bold foliage thriller that brings height and brightness.

• Training up a trellis or structure for vertical interest
• Using as a thriller in containers for height and movement
• Letting it spill over edges while climbing upward
• Pairing with dark foliage for high-contrast combinations
• Brightening large planters with strong, architectural foliage

Why Lazy Leaf Loves It

This one brings structure and color at the same time. The key lime foliage is brighter and more saturated than standard chartreuse vines, so it stands out immediately, even from a distance.

Unlike typical trailing sweet potato vines, this Upside™ variety climbs while still trailing, giving you more versatility in how you use it. As part of the Sweet Caroline series from Proven Winners®, it's bred for strong vigor, heat tolerance, and reliable performance, so it fills in quickly and keeps its color consistent all season.
