Re: zlg53 The tree looks like it may be evergreen. In which case it may be Cornus capitata. http://www.google.co.uk/images?um=1...arch&aq=f&aqi=&oq=&gs_rfai=&q=Cornus capitata Easy to tell apart at this time of year. Cornus kousa leaves go a beautiful colour in the autumn.
Ditto to Cornus kousa. The fruit are edible, can be delicious. Not C. capitata, as that wouldn't be hardy in Worcester (Massachusetts, USA - zone 6)
