So glad to see I’m not the only one to experience this. At least I know it’s not anything I did!!
Actually, I recently put 12 beans into jiffy pots, and of those 12, 2 of them are double sprouts. Both are Jungle Spice #6, which were gifted to me by the very kind and generous @lefthandseeds, who is also the breeder that hooked up @beacher for his double sprout.
Since we know this isn’t actually a one-in-a-billion occurrence, I hope some people can share the final outcome of their double sprouted plants that were grown out. Like, were they prone to hermie, or were they the same sex or not, or was one always a runt, etc.
