Cucurbita pepo. Pumpkins, acorn squash, zucchini and some ornamental "gourds" are all C. pepo. Do not grow these varieties together if saving seeds, as they can cross pollinate. (Alternatively you can hand pollinate to prevent cross pollination.) Squash fruits vary in shape, color and flavor. Flowers, seeds and growing tips of vines are all edible. All fruits can be eaten when small and immature as summer squash, and mature as winter squash. Approx. 4.5g/15 seeds per packet.
