Crape myrtles from the top: 'Centennial Spirit', 'Catawba', 'Cheyenne'
Crape myrtles are part of the reason!
It's pretty easy to find 'Catawba' in nurseries. As much as I love the others, they aren't as easy to come by. I planted 'Centennial Spirit' about 25 years ago. It was advertised as reaching 3-5 feet. It's a good bit taller but is easily kept to 10-12 feet and has a useful upright form. 'Cheyenne' is a better red, to my mind, but spreads out more. Again, it is easily kept in bounds. 'Osage', the crayola purple in the middle, spreads with age. It's another nice medium sized variety.
