What's the variety? I have Negresse, but it never produces much. I've been trying to get TPS off it; last year I had one very small berry, but it was empty. The next step is to try to graft it onto a tomato rootstock. I've only got two seeds of a rootstock variety to germinate, but I should at least be able to get seed for next year. I've got a black-skinned carrot which came from the market; I've no idea of the variety. I'm hoping to get seed off it.
