Sometimes it helps to go to a nursery with a few names in mind, but then LOOK AROUND and see what pleases your eyes. THEN go look them up and figure out whether the nursery salesperson was being helpful or trying to stick you with something that will never be happy in your climate.
You can do the same thing with neighbors: peek over fences and around corners. Find some trees that you like the looks of. If you see HEALTHY blooming trees in spring that you like, note them down.
Reverse the "Welcome Wagon" routine and bring some cookies or bread or fruit to that neighbor with something you like, and introduce yourself. Tell them you LOVE their tree, what type is it? They won't know, but then you can take pictures of leaves, bark and limb structure and ask someone else.
If you ask what kind of plants SHE likes best, and she's a gardener, you may have a garden friend for life.
Meanwhile the neighbor thinks you're perceptive and artistic for liking her tree!
