Thanks, Polly.
Val, I bought that Mahonia as an untagged distressed plant marked down at Walmart, so don't know the variety. It looked so close to dead, but revived and has grown wonderfully.
Hmmm, there are some tall thin Ilex like Sky Pencil and Daphnes like Mezereum. Be careful with Daphnes, not all are evergreen. They have varying degrees of Ph needs. I can't think of ,much else other than conifers which are columner in shape.
