Catawba Crape Myrtle gives 3 seasons of color. Deep green leaves in spring. Mid to late summer - deep purple blooms. Tip-trim the spent blooms to encourage a longer blooming cycle. A lovely bronze coats the leaves in autumn. Any flowers left to go to seed will become dark brown seed pods. Can also be trimmed into a small tree. Mature height - 10-12 feet. Spread - 8 to 12 feet and widest at the crown.
I have this tree in my front yard...i absolutely love it..just have to trim the bottom branches out as it grows because it will grow down like a bush if you dont. Texas Lilac (Vitex). They are hardy, drought tolerant, and the butterflies & bees love them.
