Info From "Tripledivideseeds long-pie-pumpkin
"Long Pie dates back to the late 1800’s. Almost lost forever, Long Pie Pumpkin was brought back to commercial production by John Navazio and Garden City Seeds in the early 1990s. These magical fruit that resemble overgrown zucchini are indeed pumpkins. The fruits range from 3-5 lbs each. In 2014 50 plants yielded over 450 lbs. They are virtually stringless and sweet. At harvest, mature fruits are green with a small orange spot. This spot is the telltale sign they are ready to harvest. Cure them as you would any other winter squash and store them in 50 F conditions. As time passes these wonderful fruit turn a bright orange. Take these bright orange fruit out of storage on those cold, grey Montana days and use in your favorite pie, bread or soup recipes. Oh, and don’t fret if the fruit you harvest do not have an orange spot. These immature fruit work great in place of zucchini in your favorite bread recipes. Original Seed Source: Fedco. Cucurbita pepo.

"New England's trusted survival food, this pumpkin stores for up to six months and grows sweeter over time. Families depended on it to see them through the harshest winters, stacked in cool cellars like insurance against hunger."
Stellareureka also sells seeds for "Superschmelz Kohlrabi" and "Redmangel beets" both of which looks interesting.
