Shepherd’s Purse is very easy to identify. Its seed pod looks just like a shepherd’s purse and nothing else looks quite like it.
Has anyone ever seen a shepherd’s purse, or even a picture of one? Maybe at a sheep museum.
Shepherd’s Purse has been used medicinally for all sorts of things. Some people still use it. It’s edible, but don’t eat a lot of it since it will make you sick, or cure you of something. These statements are all based on web searching since I’ve never ingested it. I may try this summer, just to see what it tastes like.
