The past years I just experimented growing a few tomatoplants from seeds I collected from tomatoes we ate. I know the result is probably no longer exactly the same as the tomato I collected the seeds from. I recollect something about F1 hybrids, but I never payed a lot of attention, maybe someone can explain. I want to breed coeur de boeuf tomatoes, or in Italian money; cuore de bue. Would you go for plants or grow them from seeds?
