So our first summer in this house - my first garden! Out there today, I noticed one of the shrubs/small tree type bushes has now grown berries, or fruit, on it - and was inordinately delighted to see they're heart shaped! DP has duly christened it the 'bush of love' but I suspect that's not what it is officially known as 
Any ideas? I've put a picture on profile (from which you can see the said berry/fruit and leaves) the stalks are thick and woody.
Thanks!
