Cotinus size and siting
I was hoping to plant a Cotinus in the strip along our driveway but there is not a lot of space between plants there until the bottom which gets a lot of water in spring run-off time. Can they be held to a narrow size to fit in with other plants or can I plant one on a mound toward the bottom to improve the drainage? I looked at articles on coppicing, and it sounded good but I'm afraid of making a really knobby base that would look funny. Any ideas?
