What are field peas? Are they similar to English peas?
field peas are not exactally like english peas. they are more like an immature bean. we sometime call them pink eye peas or cow peas. summer succotash down in Savannah Georgia is one of my favorite memories.
Field peas as I knew them as a child cooked up brown, like a purple-hulled pea, or more like a black-eyed pea. And the cows love field pea vines!
Pisum sativum = English peas. Vigna unguiculata = field peas. Field peas are, in fact, legumes. The following link will provide you with solid information and a photo of the brown cooked peas as described by Kayb: http://www.grist.org/article/peas-and-harmony
Field pease, afaik, are really a "bean." When they are fresh, they take somewhat longer than English peas to cook.
