Days to Maturity: 120 days
Red Grano Onion is a fast-maturing, sweet red onion variety known for its mild flavor, attractive color, and excellent fresh-eating quality. This short-day onion produces medium to large, globe-shaped bulbs with smooth, red-purple skin and crisp white flesh blushed with red rings. Ideal for southern gardeners or anyone in mild-winter climates, Red Grano matures early—typically in just 90 to 120 days from seed. Its sweet, mild flavor makes it a favorite for raw dishes, while the vibrant color adds eye-catching appeal to salads, sandwiches, and salsas. With good bolt resistance and reliable yields, it's a top choice for home gardeners seeking an easy, reliable onion crop.
Red Grano onions are best used fresh due to their relatively short storage life. They're ideal for slicing onto burgers, tossing into green salads, dicing for fresh salsa, or using in lightly cooked dishes like stir-fries and sautés. Their balanced sweetness and tender texture make them a popular choice for raw culinary uses, where a pungent onion might overwhelm.
Start seeds indoors 8 to 10 weeks before your last frost date, or sow directly in mild climates with short-day conditions. Transplant seedlings into well-drained, fertile soil in full sun, spacing 4 to 6 inches apart. Keep soil evenly moist during bulb formation. Red Grano thrives in regions with mild winters and longer daylight in early spring. While not a long-storage onion, it offers dependable bolt resistance and consistent performance in the right conditions.
