Where did this mystery squash come from?


This squash is probably the result of cross pollination between the acorn squash and the pumpkins (or any other related squash that you have grown). Both of those crops are of the same species (Cucurbita pepo) and can produce seeds pollinated by a related plant. The effects are seen in the following year when the seeds that have been saved or have fallen into the soil grow and produce an unfamiliar fruit (like yours).
