What flowering tree stays in bloom the longest?
For a long-blooming tree, it’s hard to top crape myrtle (lagerstroemia). Most southerners know that crape myrtle blooms literally all summer long, says arborist doug still. Crape myrtles not only will these trees be continuously in flower all summer long, but since they are very drought hardy they will survive a little neglect and happily grow in a container for many years. The cherry-red dynamite crape myrtle is one of the best choices for a container, growing to perhaps 10 feet tall.
