Product Details

This Italian heirloom has been available to gardeners since the late 1800s, but is hard to find in stores. The wine-colored, flattened globes are 1" high by 2"–3" in diameter. Their sweet flavor is delicious fresh or cooked—perfect for roasting and grilled kebabs.

Growing Info

Harvesting: When onion tops have fallen over and turned yellow or brown, they are ready for harvest. Harvest in the morning, lifting onions with a garden fork. Dry them in the garden in the sun for 2 to 3 days, lightly covering the bulbs with straw, or the tops of other onions to prevent sunscald. Cure onions for 3 to 7 days in a dry area with good air circulation. Once dry, cut the roots to 1/4", and the greens to 1" to create a seal, preventing decay.
