Cucurbita moschata 70 days. This Italian summer squash is a wonderful diversion from the usual. The light green-to-tan fruit can grow up to 3 feet long and may be harvested anytime, from just a few inches through its full size. Enjoy Tromboncino’s rich flavor steamed, grilled, or sliced raw in your favorite salad. A vining variety that is best trellised for straighter fruit.
