Originally posted by Robin I'll also add that when grown as a plantation or avenue, there is a pleasing symmetry to trees. London plane trees are a particular favorite for avenues around here.
I'll try to get back before the end of the day with another example of trees planted fairly closely to create an avenue, creating a mood that invites you to enter and stroll.
As promised, two views of an avenue of trees in an arboretum, done with ginkgos, the tallest specimens of that species I've ever seen. I don't know what the smaller trees are that are providing a dense wall of greenery at ground level. The third image is another path in the arboretum that looks ageless. Located on the Azores.
