Thinking out loud here, I might ignore my previous inclination to avoid fruits which may avoid wasps.
I was intending to plant a greengage and a Victoria plum elsewhere, so they are off the list for here.
But might go for a damson, or maybe a cherry.
I've got a winter flowering cherry (ornamental) and a hornbeam which were going to go in this bed, but they can go elsewhere.
So presently on the list for here is:
-blackthorn (as the site is named after them, also for the sloes)
-quince
-gooseberry
-chinese lantern
-damson
-yellow plum?
-blueberry?
-cherry?
-pomegranate 'Province'
List for elsewhere:
-greengage
-victoria plum
-hazelnut
