Red Comred onion sets are a productive and flavorful option for gardeners seeking mild-to-medium onions with beautiful color and excellent eating quality. This long-day variety thrives in northern and central regions, where extended daylight promotes firm bulb development and rich, reddish-purple skins with crisp white flesh accented by pink or purple highlights.
These Dutch-grown sets produce large, flattened globe-shaped bulbs with thin necks and a fine, strong flavor—perfect for fresh slicing into salads and sandwiches, or adding depth to cooked dishes. Vigorous and reliable, they can also be harvested young for use as scallions, offering versatile culinary possibilities. Their strong growth habit and adaptability make them a dependable choice for sustainable and organic gardens.
Plant the sets 1 inch deep and 4 inches apart in fertile, well-draining soil. Red Comred onions perform best in full sun with consistent moisture and are hardy in USDA Zones 3–9. With proper curing, they store well, maintaining flavor and texture for months.

Curing and storage
Long-day onions need enough northern summer daylight to initiate strong bulbing, so compare this type with your latitude. Reduce irrigation as tops fall, lift bulbs gently, and cure them in a dry, shaded, well-ventilated place. Trim only after necks and outer skins are thoroughly dry. Store sound bulbs in cool, dry conditions with airflow, checking periodically for softening or sprouting. Browse other onion sets to compare colors and day-length responses.
