Actually, I believe it started with pigweed and then sort of became kind of a collective plant. That is all plants with edible shoots Milkweed,chickweed,and even cattail root has young shoots.
I will tell ya what got me thinking about the difference is this. I sprout legumes, and so on, and was looking for other unusual sproutables.
Actually , going back one more step the process what really got me thinking about it was chewing on an apple seed and wondering if a apple seed, or other "fruit" seeds were sproutable. I found out that quantities of certain fruit seeds are poisonous and contain a form of cyanide but NOTHING on sprouted seeds. However, This is another topic.
I would really like to know what unusual edible plants could be sprouted to eat. However,I do not think any reliable info exist. I am not to interesting in finding out the hard way. :)
Thanks for clearing up what a shoot is.
