Supertunia® Tiara Blue has beautiful deep purple/blue flowers with a light purple center that are vigorous with slightly mounded habits that function as both fillers and spillers in containers. They are also excellent landscape plants, best suited to be placed near the front of beds. This award winner is heat and drought tolerant, attracts pollinators, and does not need to be deadheaded.

Plant in part to full sun (4+ hours daily)
Space plants 12-24 inches apart for best results
Produces vivid violet blue flowers with a white center through hard frost
Maintains green foliage spring through frost
Great for containers, edges, groundcover, landscapes and mass planting
Attracts bees, butterflies, and hummingbirds
Heat tolerant, continuous bloomer, long blooming, 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. Give a light trim anytime you think it's needed or at least once in July and once in August. Never trim off more than 20% of the branches.
