Planting under blackberry?

[kentishgal]

Ive just planted a Loch Ness Blackberry in a semi circular bed (about 2ft wide and 1ft deep). I want to plant something in the space beneath but am wondering if its ok to do so??, is there anything that I shouldnt plant??
(I was thinking about something like borrage or mint which would be contained by the concrete bed).

just remember you may get torn to shreds when harvesting your herbs

I haven't got anything under my blackberries, I use grass clipping etc to keep everything moist but I don't think planting a herb as ground cover will do your brambles much harm - although borage self-seeds everywhere and is a huge plant, 3ft x2ft!!

Blackberries up the back wall of my garage/workshop, underplanted with rhubarb.

The rhubarb can mostly be harvested before too many new blackberry canes emerge, and the old blackberry canes are tied up mostly out of the way.
