undersowing fruit bushes

undersowing fruit bushes

Has anybody here planted ground cover between fruit bushes? I already have rhubarb and comfrey alongside my blackberry. Now I'm thinking about planting something alongside my raspberries, gooseberries, jostaberry and tayberry. More comfrey? One of the clovers? Suggestions would be most welcome. I'm in Northern England on a heavy loam.
