Cucurbita moschata 100 days. Autumn Frost yields very heavy harvests of attractive, blocky, tawny-colored fruit with a dusting of natural waxy bloom. Growing to about 6 inches across and 4 pounds each, these deeply ridged beauties offer a thick layer of sweet flesh that maintains its high Brix into the New Year. The vining plants produce 9‒10 fruit that start out green and ripen to their frosty finish that are pretty enough for your fall decor. Approximately 15 seeds per gram. IR: PM.
