I'm wanting to cut these old columnar cheery trees down and replace with another type of columnar tree. Don't think I'd like an evergreen as the sun comes from that direction in winter. Location is in western Washington State. This garden is on the south side of our property. The home you see is the neighbors.
I saw Twomblys Sentinel Acer but I'm thinking at mature tree will be too wide. Trying to get the right tree of the space.
