Just in case your not from around these parts, the Crepe Myrtle is Arkansas' premier flowering shrub (or tree) throughout the blistering summer. I tend to associate the start of Myrtle season with the Fourth of July, when the Crepes explode like so many Roman Candles.
As is, Myrtles come in at least four colors: Cumulo White, Cotton Candy pink, Ruby Red, and Dark Lavender. As for shape, they range from sprigs and sprays to big bushes or even full blown trees, as shaped by pruning.
