Growing directions

Direct sow 1 inch deep in loose, well-drained, fertile soil in full sun with a trellis or fence for the tall vines; Sugar Snap Pea was bred by Calvin Lamborn and introduced in 1979, winning the All-America Selections award and transforming the edible-pod pea category — it combined the thick, succulent, fleshy pod of snow peas with the full, plump, sweet peas inside, creating a pod that is outstanding eaten raw, pod-and-all, with no tough strings to remove at the right harvest stage. The crisp snap when a mature pod is broken — and the burst of sweetness from the swollen peas inside — made Sugar Snap immediately distinctive from flat snow peas. Harvest when pods are round and full but still bright green before the pod skin begins to wrinkle; at this stage the natural sugars are at their peak. Overmature pods develop a tough string along the suture and the peas inside become starchy. In zone 9 Sugar Snap pea is primarily a January–April crop that provides the most rewarding fresh vegetable of the cool season.
