Today I began an illustration of Golden Bush Scallops, a type of summer squash:
As all forms of C. pepo are pollinated by bees, cross with one another freely, and produce fully fertile offspring, it is amazing that most of the summer squash groups have maintained their identity for hundred of years. In the scallop group...the fruit are flat, with scalloped margins. The history of this group in Europe dates to the middle of the 16th century.
The SESE catalog offers a lot of open-pollinated seeds, (98% of their seeds), because one who wishes to grow the veggies of an open-pollinated seed and then save the seed from what they grow can do it and get similar plants. But this is not the case with hybridized seed. For a thorough explanation of this check out their website: http://www.southernexposure.com/open-pollination-ezp-19.html. They also prefer open-pollinated over genetically modified.
