Gee, thanks for the difference in leaf structure: that made it so EASY to tell which was which. I grouped Rosella Crimson and Bella Rosa seedlings together and easily separated by what exctly they weere!
Although I had started the same numbefr of each, I wound up with only one Rosella Crimson:a sturdy little tree with rugose leaves!! Very healthy!! The rest were regular-leaf, with the normal tall waving branches of a regular (non-dwarf) tomato: Bella Rosa.
Will seeds saved from Rosella Crimson come true?? I can see that I'll need to start MORE than I usually ddo (If it is a "keeper" for my garden re diseases and taste).
