I finally narrowed my list down to a half dozen:
Two are going to be early-season and late-season tomatoes that produce quickly and a little more tolerant of cool weather:
- 42-day Tomato, Early-producing, cold-tolerant cherry, determinate plants. Can be container-grown, so an option for a late-season tomato grown in a container or two.
- Stupice, cold-tolerant early indeterminate potato-leaf type, small to medium salad tomatoes.
Goliath Bush Early, reputedly produces medium to large beefsteak tomatoes on a determinate plant 24 to 36 inches tall, also suitable for containers.
Main season:
- Purple Ukraine (recommended by some of you), large purple plum-shaped.
- Hawaiian Pineapple Large beefsteak, yellow with some pink, fruity (compared to pineapple).
- Marmande Also recommended by some of you, red beefsteak.
All of the above are recommended for their flavor. Other than container plants, I will likely grow just 2 or 3 of each of these this season. I'm also sharing some of the seeds with my sister in Indiana. I will leave enough seeds for the next season or two.
Many of your other recommendations I have saved for another year, though I can't find a few of them in the USA (such as Dívčí Prs; no luck with Orange Russian either).
