fruits?

[Madasafish]

Whatever you do, do not buy Himalayan blackberries. They are tall and very thorny...

The new raspberry from Marshalls would be a good choice as it is clump forming and would not need the control that ordinary raspberries need. And the fruits are a pretty purple, however it is not cheap. Another good one to go with blueberries is cranberry as they both need ericatious compost.
