|This crapemyrtle grows in the tree form and can get as large as 75 feet. Late spring to early fall produces purple to white flowers with little cold hardiness. Seed heads follow flowers and persist throught the winter, adding an ornamental quality. Fall color ranges from orange to red, and smooth grey to reddish-brown bark is attractive year round.
Crepe myrtles should be grown in fertile, well-drained soil in full sun, in open areas where air circulation is good. In cooler areas, the crepe myrtle is grown more like a flowering shrub, that is pruned back hard to the ground each year. This is a massive no-no in zones 6b and higher. Prune to encourage a tree-like form, removing only suckering inner shoots, crossing branches, and side shoots 4 to 8 feet from the ground. If you can't remove side shoots with hand pruners, you should probably leave them. Lower suckers may be removed with loppers.
