I want to plant a Smoke bush in my back yard and I am looking for suggestions. I love the hazy pink inflorescences and the rounded purple leaves. I am in zone 8 and the back yard gets 5 to 6 hours of direct sunlight from the West. Drainage is excellent for the location. I am looking for a variety that is more shrub-like and will stop growing at 10 to 15 feet in height.
