Crape myrtle shrubs love the hot days of summer, and after the nice rains of June, they are producing a spectacular show across Oklahoma this year. I truly believe they should be our state shrub and some community should plant them extensively and then host a big crape myrtle festival.
Crape myrtles bloom for many weeks starting in late June, often putting on a colorful flower show into early fall.

He has already introduced many exciting new varieties to the national market from his breathtaking crape myrtle fields at Stillwater.
