Santero F1 - Disease Resistant Main Crop (200 seeds est)

A Breakthrough in Reliability – The Ultimate Solution for Downy Mildew.

For the modern kitchen gardener, Onion Santero F1 is nothing short of a game-changer. It is one of the very first varieties specifically bred for high resistance to Onion Downy Mildew—the scourge of allotment holders that can ruin an entire crop in a single damp summer. With Santero in your garden, you can grow with confidence, knowing your plants are armored against the elements.

Each pack contains 200 seeds, promising a high-yielding harvest of professional-quality bulbs. These onions are classically beautiful, featuring thick, copper-golden skins and a perfect globe-to-slightly-flat shape. Inside, the flesh is crisp, white, and exceptionally firm. Santero is a true maincrop variety, renowned for its "thin necks" that dry down perfectly, leading to superior storage potential that will see you through the winter.

Why 'Santero F1' is a garden essential:

• Superior Disease Resistance: Built-in protection against Downy Mildew, reducing the need for treatments and ensuring a healthy, green canopy all season.

• Exceptional Storage: Famous for its long shelf life; when properly cured, these bulbs remain firm and flavorful for months after harvest.

• Vigorous & High Yielding: As an F1 hybrid, it possesses "hybrid vigor," growing faster and more uniformly than traditional open-pollinated varieties.

• Versatile Kitchen Staple: A robust, medium-strong flavor that holds up beautifully in stews and roasts, yet remains sweet enough for classic onion soups.
