Crepe Myrtles in the PNW? - Absolutely! The one I planted in Sammamish reached 12' over a 15 year period, and was pruned to a tree form. It was sited in full sun, in amended clay-based soil with sharp drainage. Never had any disease, pest problems or limb-loss from winter weather. They are not widely planted here; I suppose that is because many people don't know about them. Wells Medina has sold them for many years; their selections are hardy for the general 7 / 8 zoning. Because of the way my property was sited in Sammamish (very exposed), I was considered zone 6. If you have the room & the determination, I would definitely recommend planting one. Gorgeous form & blooms - worth the effort!
