Hello fellow heirloom lovers! I've been growing primarily heirloom varieties (as finances allowed, previously) for many years, as well as organic gardening and this year I am dedicated to using ONLY heirlooms, since the proliferation of genetically modified seeds has gotten so huge (thank you, Monsanto...*shudder) and as yet since there are no labeling laws we can't even know WHAT they have spliced into our food! I mean, really. Sure it would be nice to grow tomatoes that I didn't have to fight the horned worms for, but eating tomatoes that are spliced with horned worm genes? NOT!!! So, for you heirloom aficionados here, can you please help me understand if there is a way to better identify naturally created hybrids from laboratory created varieties? Are there such seeds that may not be "heirloom" but still safe to grow and eat?
