I tried to grow it last year..but germination was zero

It seems to me that that might be due to your seed source, assuming all your other tomatoes germinated well.
What was your seed source?
Tania, Jeff C grew it and liked it, I guess, but I also told him what I thought of it and you don't see it listed in the Yearbook do you?
Bill didn't like it that much and I don't know about Neil L, but Neil, you know you could post here from time to time if you wanted to.
Cathy, Green Cherry is at the opposite end of the poles as regards Green Grape the way I see it. But as with all varieties, you have to grow it to see if you like it.
Is anyone offering it commercially? I haven't seen it but there's no way that I can look at all seed sources to monitor that.
