I think it is Cornus kousa. You are very lucky because they are not that common in the UK as they need neutral to acid soils. I have never seen the fruits in the UK. Where did you see it? In the Cambridge Botanical Gardens?

Here is a link that might be useful: Cornus kousa

Hi, yes that's it.
The plant is a quite big tree, located in the countryside around Cambridge, more or less here:

Oh the wonders of the web! You live in the US spot a plant in the UK. Google maps in German (?). And get an answer back from the UK. Did you take tea in the tea gardens at Granchester?

Hi flora,
actually I live in Austria, that's why I use google maps in german. I registered at the forum with a US address because of some forum restrictions.
And I am italian.
I went to Cambridge to visit an Italian-Argentinian couple, a couple from Spain, a friend from US and one more from Australia.
No joke!
Yes, we took the last two raisin cakes at the Orchards Garden that day. Yum yum.

ciao, leodp
