That's what I was afraid of. Even so, I'm going to plant them and see what I get. I can't wait to see what they do now!
Oh, Absolutely!!!
Plant them and if they grow true, you could have a really valuable tomato resource.
The majority of the heirlooms were ‘discovered’ and were cultured by someone doing exactly as you are doing.
Selection - even among heirlooms - year after year is how we improve them. Always select those with the best characteristics for next year.
