In previous years I have found a few that I didn't care for, and one that I absolutely will not plant again. I hated Homestead tomatoes. They tasted like store-bought. Yuck! I haven't had luck with white varieties as they tend to go bad before we get a chance to try them (zero shelf life on the Great Whites we grew a few years ago). I have largely been putting off green tomatoes for a while now. If it doesn't show me it's ready to pick - I won't stop to check ripeness, and I'm afraid it would just be a complete waste as the green ones pass their ripe stage and rot on the vines while I'm fawning over my pretty pinks and stripes.
I have had a few that were winners. I got some seeds labeled "Pink Sunshine" from wintersown, and they were wonderful. Unfortunately, I planted my seeds and then the ones I saved the second year all turned black. Now I'm stuck growing out my seed mix in hopes of regrowing my favorite variety. It doesn't seem to exist anywhere else, as I have been unsuccessful in tracking down any other source. And the blondkopfchen was so productive it was stunning! It produced enough to keep my kids eating tomatoes all year. between these two varieties, even my "I don't like tomatoes" kids were happily munching on tomatoes in the garden. We also grew a variety called Solanum spontaneum that was supposed to be highly productive. We made the mistake of planting them at my parents' house and the deer got most of them, which had us fighting over the few tiny tomato berries that managed to grow through the fence and out of the reach of the deer. Those were wonderful too.
So we are starting to gain a "plant this one again" and a "no thank you" list over the years. I'm not saying I wouldn't try white tomatoes again, or green tomatoes in the future, but I certainly will never plant Homestead tomatoes again. Bland! I also don't like that determinate varieties produce all at once. This would be great if we were canning or making sauce (which is the plan for the future), but when it's fresh eating tomatoes, it gets monotonous. I prefer my indeterminate varieties where we can eat one from this plant and a few from that plant and then try another variety from another plant and it gives the plants time to ripen the next fruit.
I think this year we might again try some side-by-side trials. I had wanted to do them before but either seeds didn't come up, or we had to change plans due to a move... But next year we should be in the clear!
I want to try three versions of pear tomato. We have Chocolate, Red, and Yellow pear, and I want to grow them out in a row to try them, literally side by side. I'm also considering a similar head-to-head with cherry tomatoes. We have black cherry, chocolate cherry, and red and yellow cherry varieties. I'm most interested in the two dark ones, but it wouldn't be a fair contest without the more classic colors too. I want to try a few different paste tomatoes too, just to see which ones taste better and which ones produce better. Cow's Tit is definitely on that list, but I'm not sure what other varieties to include against it.
Have suggestions? Want us to try a variety? Let me know!
