Columnar Oak Characteristics
If I select “Kindred Spirit” Oak trees for a screen in a modern, residential landscape design: 1-how many years will the trees retain their leaves through the fall/winter? (I heard these oaks retain leaves while they young, but then, they live 150 years - how long is young?) 2-does this oak have acorns? How many on a scale from excessive to inconsequential? 3- are there any other columnar oak varieties I might consider?(wants: columnar, screen, retain leaves, native, pretty) Thanks!
