Can’t pick between green or purple for your container spiller? Why not have both—with flair? Sweet Caroline Sweetheart Shadowstorm™ is your go-to for a touch of drama and a whole lot of charm. Its heart-shaped leaves emerge a fresh green and slowly reveal a moody masterpiece of deep, near-black with speckled green accents—each leaf a little surprise from Mother Nature herself.

Unlike older variegated varieties that need constant haircuts to stay cute, Shadowstorm™ keeps its act together with a naturally fuller, bushier shape. It grows with the grace of a well-kept secret: no scraggly vines, no high maintenance—just effortless beauty from spring through fall.

  • 6-16 inches tall and 20-36 inches wide at maturity
  • Annual except in zone 11, be sure to check your USDA zone to ensure success
  • Plant in part to full sun (4+ Hours)
  • Space plants 10-18 inches apart for best results
  • Maintains purple-black foliage with green variegation from spring to frost
  • Great for borders, containers, groundcover, landscapes and mass plantings
  • Foliage interest, heat tolerant, deadheading not necessary

The Eco+Grande features nutrients embedded in the container walls, which help plants grow bigger and faster throughout the season when planted in the ground. Be sure to remove the tabs from the container before planting. If you choose to plant in a container, we recommend taking the plant out of the Eco+Grande, breaking it apart, and mixing it into the soil at the time of planting. When the Proven Winners Eco+Grande container is discarded in the garbage can, it will naturally break down faster in a landfill than a traditional petroleum made container. The container will get smaller and smaller until microbes consume it, turning it back into an inert organic product. Learn more about this in our blog.

Care: Fertilize weekly with Proven Winners Water Soluble Plant Food for best performance. Prune to shape as desired throughout the season.
