Pumpkin Flowers are delicious in Salad, I have two massive pumpkin vines going crazy in the garden. There are some little pumpkins growing but I am not sure how well. Apparently Pumpkins have male and female flowers and sometimes you need to propagate them. More on that later.
but the flowers are great in Salad. Pick them early in the morning and pop them into a ziplock bag. Keep in the fridge till you are ready to make your salad. Wash and dry the flowers carefully. Its easiest in a salad spinner, then tear into nice size pieces and put them on top of your green salad. Looks fantastic and has nice mild pumpkin flavour.
