Talking to a client today who was trying to describe a tree that he has seen at a friends house in Mass. Says it is a "decent sized tree" which I have narrowed down to be maybe 20 - 25' tall? with green leaves and a white flower that sits on top of the leaves. He called his friend and asked what it was and the reply was "I was told it is a Korean crab tree". I can't really picture what this might be. The client I was talking to is aware of what a typical flowering crab is and doesn't seem to think this was it. His description reminded me of a flowering dogwood but he claims it was not this. Anyone have any suggestions as to what he may be referring to?
