The tree dahlia (Dahlia imperialis) is a unique 12 foot tall true dahlia from Central America that has large pink (or white) flowers in November. Cut back to the ground every winter, the tree dahlia sprouts back in the Spring with several shoots, creating a large root mass when planted in the ground. It's best planted in the background near a fence where it doesn't block other plants and gets some protection from the wind. One year, an early storm shredded my tree dahlias just as they started to bloom. An early frost can burn the plants before they're finished flowering. But the risks are out weighed by the reward of seeing a profusion of 6 inch pink flowers 12 feet in the air at a time when most flowers are long gone.
