As a legume, they put a considerable supply of nitrogen back into the soil. That makes these peas an excellent rotation crop to plant between spring and fall gardens. Drought-resistance and low water requirements make it an ideal crop for our hot Gulf Coast summers.
Don’t know why they’re called “southern” peas. Does that mean that only people in the south eat them? They’re also called “cowpeas”, because they were also used as cattle feed. However, give me a plate of purple hulls cooked down with some bacon and onions (and a little jalapeno thrown in for good measure), add a pork chop and some fresh tomatoes, and I’m in heaven. I’ve been known to make a meal out of purple hulls and bread. And crowder peas are my absolute favorite.
