Here I thought I was being all helpful and stuff, thinking that the cucumbers must have been mislabeled or something! I didn't know regular cucumbers did that!
I would trust Lesa's response as this is my first time growing cucumbers and my pickling cucumbers are just starting to grow (they're very cute right now - only about half an inch long). There's a lot for me to learn about growing vegetables and the people on this forum have been so great.
