Presumably with your nickname you are at Cambourne in Cambridgeshire. If so, there are lots of bushes growing in the hedgerows and in May/June you can pick flowers in abundance, certainly all along the Devils Ditch footpath near Newmarket. No need to buy a bush because they get very large, the berries seed themselves everywhere and you will know when they are ripe because your car/washing etc will be covered with bird excrement after they have had a good feed.
