Alma, They are an heirloom from Botanical Interests. I think I bought the packet at Summer Winds. Latin name is: Cucurbita pepo.
The zucchini is also from the same vendor and is called Balck Beauty Zucchini (cucurbita pepo also.....how can that be?????). It's not warted and very tasty. Ate the first one off the vine yesterday. Tiny baby squash.
