70 Days. Snap peas are best eaten fresh and there’s nothing like picking them right off the vine. No need to shell them; the pods are crisp, sweet and tender! 'Sugar Snap' is an All-America Selections winner that provides an extended harvest of thick, crunchy 3" pods filled with flavorful peas. Green peas are a good source of vitamins A, C, K, and B and iron, folic acid, and many minerals. Vines tolerate some heat. Grow 6'–8' climbing vines on poles or a trellis.
