What exactly is poke?
As in poke salad Annie, gator got your granny (TJ White). Is it some sort of wild green?
Poke salet (salad is an alternative spelling) is another name for pokeweed. It is a plant that has been used both for food and medicinal purposes going back the the native Americans. The whole plant, especially the berries, is poisonous if not cooked. The leaves are prized by some folks and are, in my experience, used as a complement to turnip or other greens.
When I was a little boy, my grandmother picked some one day and cooked it for supper, but apparently didn't cook it long enough. She and my grandfather became horribly ill, were hallucinating, and spent a couple of days in the hospital. You can Google poke salet and find out all you would ever want to know about it.
I think you have to pick the leaves when young.And yes,the berries are poisionous.The FoxFire series of books by Elliot Wiggington have about various plants like poke greens,plantains
which are not poisionous,dandelions, wild mustard,etc and recipes.If you want to try poke greens,you can buy them already canned.I think it's The Allens brand or google canned poke greens to see brand names.Canned poke greens can be found I imagine mainly in the south.
Then theres the classic Tony White song "Poke Salad Annie"(Polk Salad)
Elvis also recorded this song
