Shell/English peas or snap peas? I don't grow any spring crop peas and only do Fall plantings when I have tons of room to devote to them so that the production is worth all the space required.

That said, the main problem is heat tolerance and powdery mildew resistance. For shell peas Green Arrow and Maestro are my 2 preferred as both have strong resistance to PM and are fairly heat tolerant. Both are 65 day +/- DTM.

For snaps I've read that Super Sugar Snap has high tolerance and resistance but never tried them myself as they are 6 footers so require good support and lots of room.

Every summer we plant peas at the end of July when the garlic comes out, and harvest from late September until a killing frost. We've had good luck with Cascadia snap, and Oregon Giant snow.
