NON-GMO, open pollinated, heirloom. 35-50 days. The smooth and rich-green leaves of these spinach plants help provide this heirloom’s name— as Giant Noble Spinach leaves grow 25” long! Also known as “Smooth Leaf Spinach” this verdant and subtly sweet vegetable produces for a long summer harvest and gives a savory flavor when cooked. Excellent variety for canning or freezing. The big thick leaves hold up well.
