When we lived in Texas, we had two amazing crape myrtle bushes on our front lawn. The plans themselves are interesting all year round, and the blooms are really pretty.
When we moved to Indiana, we assumed it was just too cold here and never tried to plant them. Then, we saw these plants on the grounds of the IMA and realized, that maybe we were wrong.
I did a little research and it turns out they need a bit more love then they did in Texas, you have to cut them back each winter, but I think they might just be worth the effort.
