Here's an early Sunday morning photo of the whole bush that was only sticks less than 12 inches tall when I planted it in early May this year. The pot I purchased at a local nursery turned out to be two bushes so I divided them, one for the front and one for the back. The one in the back shown here got less deer damage and that surprises me. The one in the front is close to the road and I have never seen deer in that area. Who knows what happens when you are sleeping, right?
A friend sent me a photo of hers at her vacation home in Stockbridge, MA. It's at least 10 years old and it's huge.
Her photo makes me reconsider the placement of my shrub. If they like where they are planted they can reach for the sky. Of course, you can control the size by pruning in late fall or early spring.
