A good way to start would be to all make lists of what we already know to be common weeds that are edible.
Photos would also be helpful, but not essential, that is something that those that are committed can go out and research for themselves (if they don't already know exactly what the common weed already is) once they have the name.
Some of the ones that have been mentioned so far are
- Young grape leaves
I'm trying to get my hands on a copy of Isabell Shippard's books 'how can i use herbs in my daily life' and 'how can i be prepared with self-sufficiency and survival foods?' these are jam packed with the edibles.
Green Smoothies are an important part of my diet, i travel a lot and people don't always have the usual cultivated greens in their garden, so often i go off and find what ever weeds i can to get my green hit. I too am after a sturdy list.
look forward to learning form you.
