You should be ok. That said, 7b can feel colder depending on exposure to prevailing winds, shade, etc.
Keep in mind that crape myrtle roots like to go wandering and will pop up a new plant here and there. In my area crapes are pruned in February while they are dormant. That's about two months before last frost (sometime in April).
That's a really pretty color! Do you have the variety name?
