The scoop on Dahlia Imperialis | Tree Dahlia

If you've heard of "tree dahlias" these are the plants being referenced. Maturing to a huge 8-18 feet in a single season, Dahlia Imperialis looks like nothing you've ever seen before. Six inch pink flowers are held in loose groups that are 2-3 feet across. Plant where growing season are very long (or extend the season by starting indoors) - these dahlias need 7-8 months to blooms. Some gardeners grow for the bamboo-like stems and use for landscape effect. Happy in mild West Coast locations where they grow with wild abandon.
