Scallion
Allium fistulosum
Zones 3–10
Growing
Unlike common onions, these scallions never develop a distinct bulb, instead producing single upright, hollow stems that suit container gardening. Start your crop from seed or by dividing existing clumps. Keep the soil well-drained with a pH between 6.0 and 7.5. Because this is a cool-season crop, it is hardy and can survive a hard freeze, making it reliable for early spring harvests or late fall plantings.
To harvest, pick the stems when they reach your desired size, as they do not continue to ripen after being cut. Use the white portions for deeper flavor in stews or stir-fries, and the green tops as a fresh garnish for soups and meats. If you have an abundance, pickle the scallions or blanch them before freezing. To keep them fresh in the refrigerator, store them unwashed to prevent premature rot.
