Sweet Caroline Sweetheart Shadowstorm Sweet Potato Vine | Proven Winners®

Why choose between green or purple sweet potato vines when you can enjoy both in one plant? Sweet Caroline Sweetheart Shadowstorm™ delivers dramatic purple-black, heart-shaped foliage flecked with green variegation, making each leaf a unique work of art. Unlike older variegated varieties, this selection has a fuller, more refined habit that requires less trimming and maintains a lush, polished look throughout the season.

As the plant matures, new leaves emerge green before developing their striking pattern with exposure to sunlight. Solid-colored leaves can be removed for a cleaner appearance, though they won’t affect the plant’s vigor if left in place. Its trailing growth makes it perfect for spilling out of hanging baskets, patio containers, and window boxes, while its adaptability to sun or shade also makes it a versatile annual groundcover in the landscape.

This ornamental sweet potato vine is heat tolerant, low maintenance, and self-cleaning, thriving with average water and minimal care. Though it may occasionally produce small, starchy tubers, these are bred for ornamental purposes and are not ideal for eating. With its bold texture and rich color, Shadowstorm™ is a standout foliage plant that elevates both containers and garden beds from spring through frost.
