I know that Lowe's should be just about to clearance their plants, if they still have any left. Our fall shipments of trees will be arriving here in late August. I would check those stores. Razzle Dazzle is the variety most of our stores carry. They top out around 4', but bloom in July rather than in the fall.

I have NEW ORLEANS. It is an orchid like color. It was slow to take off the first year. It finally got 2 and 1/2 feet tall, but spread out about 5 feet. I had to move it out of the flower bed to a place where it could do its own thing without covering its neighbors.
