LOVE THIS: Wisteria Tree. Planting one now. Just stake your Wisteria & keep it pruned back each year. The vine will eventually grow into a tree. I'd estimate this Wisteria tree to be over 20 years old.
Vitex / Chaste tree -Grows well in Texas. Deer will not touch it, drought will not droop it and if it gets too tall you can cut it back hard since it blooms on new wood. Looks amazing mixed in with grasses and Knockout roses.
