Continuing a recent theme involving crape myrtles, here is an aspect of some varieties that cannot be overlooked:
About this time every year (mid July in central North Carolina) the crape myrtles begin to drop their outer layer of gray bark naturally. For some varieties (this one is ‘Osage’), a striking cinnamon color is revealed which will last well into late fall and winter. The new bark of many crape myrtles is a quiet gray, but, when you see one that exhibits this color of new bark, it is a most attractive feature.
You may want to visit the Crape Myrtle Gallery published by the US National Arboretum that includes bark color among other attributes for many varieties.
