I'm sure this must come up a lot, but I have recently seen a tree which I would love to plant in my own garden. Someone has suggested it's a Rowan, but there aren't any thorns, or a mountain ash. But the leaves look different to any I can see on the websites. I really like the light green of the leaves and, the height and the spread, the shading the foliage provides. I like this tree. Any help would be greatly appreciated.
