trees for backyard
I'm starting to design the backbone of my backyard and so as things go, trees will serve as the anchors. This yard is small, no wider than 30 ft and not deep - possibly under 25'. So I had spoken to a landscaper and I was rather surprised that this fellow recommended an ash. I would like a tree to shield us from our neighbors but this tree would be gigantic. Anyway, this landscaper is not a horticulturalist nor a gardener. His expertise is the hardscapes - so this isn't surprising. Still doing my research, I watched Sarah's House (Sarah Richardson)in an episode that showed the landscapers redesign the backyard. I was very surprised to see that they recommended a Katsura to flank the deck that abuts the house. I must be missing something because these trees grow to a height of 80 ft.
Anyway... I'm confused. All I want is a tree that grows to 30 ft. No higher. No cherries, appleblossoms, pears,no helicopter seeds (out linden), no fragrance. Need some suggestions. Thanks.
