  1. So will the pumpkin you pictured above produce those greenish seeds you always see at the store?

    I’ve always wondered why my pumkin seeds always looked so different from the ones you find in the bulk isle.

  2. Yup, supposedly so, although, I imagine commercial pumpkin seed manufacturers just have a way of taking off the husk, ’cause I don’t think the “lady godiva” is the only pumpkin used for seeds.
    I am going to try to grow some this year though. They are very pretty!

  3. They are pretty! I wonder if the flesh would be tasty in, say, a pumpkin soup or risotto or pie as well?

    We like to toast our pumpkin seeds in a skillet with just a teensy bit of oil, then toss with salt and Indian spices. Very tasty, indeed!
