Victory seeds has a number of possibilities and good descriptions.
I just traded for zipper creams. I know they are an old heirloom in the south, but I don't know much more than that.
Hope this helps.

Here is a link that might be useful: Victory Seeds

From the descriptions I think it might be this seed listed at Victory Seeds:
Texas Cream 8
Bush-type pea with oblong, kidney shaped peas when dried. Nice garden pea that produces a nice crop.

I was sent some Zipper Pea seeds and it definitely is not the one my fil grew.

Thanks for the response.

hi. the zipper pea was a favorite of my grandmothers. heirloomacresseeds.com offers these in there catalog.

I have just learned of cream peas and have planted some. but we don't know how to cook them.

I too recently received a bag of these peas. Any suggestions on how to cook them?

I grew up eating these peas. I cook (fresh frozen & thawed) them in a medium pot with enough water to cover plus 1/2". Add salt, pepper and a small bit of salt pork or bacon. Cook on low to medium low heat until the water is just below the top of the peas. The flavor is delicate so you don't want to over season or over cook these little guys. Hope you enjoy!
