Can you help to identify these two pumpkins? I planted some left over pumpkins and moldy squash, some home grown and others boughten, in our garden last spring and here are two of the items that grew.

I did some online research:

My best guess for the white pumpkins is either Flat White Boer or Lumina, as the fruit stem appears to be smooth and “spongy”, consistent with C. maxima species, vs hard and ridged. They are about 10” in diameter and 7 “ high. The seeds are smooth along the edges.

I am at a loss for the orange pumpkin. Based on the stem being hard and ridged, I’m guessing it is of C. pepo species.

In particular, are they safe to eat?
