I bought a Delicata squash last year at the grocery store. Saved the seeds, and planted them in the garden this year. This is a picture of what developed. How can this happen? Another gardening site suggested that I got the seeds mixed up. No -- these were the only seeds in my house. I took them out of the Delicata, dried them, put them in a jar for a year, and planted them this year. NO OTHER seeds were in the house.
