Ramp is common all throughout the South. May be related to the Lily, but they look and cook like scallions, although maybe a little stronger and leaning toward Garlic in flavor. They grow wild and are seldom seen in stores.
Poke Salet is common even around here, although the Gullahs usually gravitate to Mustard or Collard greens instead.
Poke plants are poisonous, and some say that once they're boiled (forever, if they're anything like Collard greens) the water is poisonous so they're rinsed once or twice before being served. Personally, I'd stick with Collards (which are really tasty if prepared as the Gullahs do....boiled for a while and then sauteed in bacon grease. Sounds awful, but taste like heaven.
If you're a Northerner, you might try "country" Endive instead. You don't have to cook them, and they're much better (and less bitter) if the leaves (shoots) are young and tender (shorter than 4" and picked before June). GREAT in salads and I've even seen them served (as Endive ) in fancy, $$$$$, restaurants. Truth is, all they are is Dandelion leaves, but they're pretty tasty and we had them in salads ever since I was a little kid on the farm in Massachusetts and Vermont, often with just lemon juice as a dressing.
