Usually grow Sugar Snap, this year we tried one called Cascadia. It didn't set any flowers or pods on the bottom 3 ft of the plant. Taste was on par, but not production. Supposed to tolerate summer heat better than others, so it might do better for you in NC. I'll be back to Sugar Snap next year.
Also tried a very cool snow pea, Chris, called Norli. It's a Dutch variety which is extremely compact but bushy, early and loaded with small pods. Very nice yield at the farm, and they also came back from the roots and flowered and set again in the fall in my garden.
Such a nice yield from a short bushy plant, I'm thinking to try it indoors in the winter. A couple of people thought it was not the sweetest, the pods are small, and they do go limp pretty soon after picking. None of that will matter to me, if I can get a few plants to produce on the windowsill.
There's no fresh snow pea like the only one in town..
