These walking onion seeds come from the fields of a certified organic farm where I work. This plant grows a seed head at the top of a stalk and then the weight leans the stalk over to make the seeds touch the ground and send out roots to make new plants. Leaf shoots are edible but hard to chew. The main part chosen to eat is the root, like normal onions. Order gives you a handful to start your own perrenial walking onion. They are cold hardy to at least zone 7 maybe higher north.
Happy with the amount sent. It also rooted and looking good by now
