Lol, I know, ooojen.When I posted, I hadn't seen your post yet, WK. I wasn't dismissing your answer by asking whether anyone in the PNW had ideas! Good pollination information!
Greenwick - Planting seeds saved from local pumpkins could be your issue. Hybrid pumpkins can produce sterile seeds or seeds for very non-productive plants. You and your roommate could take seeds from the same pumpkin and get entirely different plants out of them. Even cross-pollinated non-hybrids-- same species but with different forms -- can give you a very wide variety of offspring. You might just have inferior seeds that grew into less productive plants. But you still have some time if you can find some female flowers! Best of luck!
Yes, I agree with the whole saved seeds thing. Many people don't realize, that if a pumpkin flower is pollinated with another flower's pollen from the same family type, that that pumpkin will grow fine, but it's seeds will grow a plant that is a hybrid of whatever the other pollen was and the original plant. Cross pollination affects what that pumpkin's seeds will do. Sometimes, if you plant seeds from a pumpkin that was set by cross pollination, you could get something cool, like a pumpkin with a different shape or color...or some pumpkin/squash hybrid...but like ooojen said, it could also be a bad match of the two original plants that will give you a not so healthy new plant from the seeds.
The only way you can be safe to reuse seeds and get the same pumpkin growing from them, is if you have made sure no cross pollination could have happened by growing a far distance from other seed family plants (so insects/bees can't bring over other pollen), covering before and after hand pollination, making sure only you, and no insects are pollinating, ect., for absolutely sure. Otherwise, there is always a risk for cross pollination and pumpkins that will have hybrid seeds.
