They’re different to grow than green beans. Here’s a few I planted in a pot, just for the curiosity of what they’d do in a pot.
They’re also planted among the green beans both on the trellis and on the rabbit fence. They come up at about the same time as the green beans but the plants grow slower after germinating. They’re also a more robust plant, leaves and vines both. They’re climbing well now in both places, and producing lots of beans pods. (We call them black eyed peas, but they’re really a bean.)
In the winter I was experimenting with seeds from the grocery store. https://sarasinart.net/2013/02/15/seeds-from-the-grocery-store/ This is a result of that experimentation, cos these black eyed pea seeds came right out of a bag from the store. Evidently black eyed peas are not the kind of thing that get genetically modified, since the seeds from the store will produce both plants and beans.
Good luck with your gardening. Growing food is such a rewarding thing!
