This African heirloom brings genuine history to the vegetable garden. The pinkish-purple bulbs are distinctive enough to make you look twice at the harvest, and their quality and keeping ability mean you can enjoy them for months after picking. Its short-day breeding makes it a natural fit for gardeners in northern climates where many traditional onion varieties struggle, and the fact that it has traveled from a small Nigerien village to seed catalogs across the world speaks to its genuine merit as a crop.
As a culinary onion, the Violet De Galmi is suited to any preparation where you'd use a storage onion: roasting, caramelizing, adding to soups and stews, or slicing raw into salads where its pinkish hue adds visual interest. Its robust flavor and solid keeping ability make it especially valuable for cooks who want to preserve the season's harvest for use throughout fall and winter.

Start seeds indoors 6 to 8 weeks before your last frost date in a warm spot maintaining 50 to 70°F. Transplant seedlings when they have developed 2 to 3 true leaves and the soil outside has warmed.
Harden off seedlings gradually over 7 to 10 days. Transplant once soil is workable in spring and daytime temperatures consistently reach 45°F or warmer. Space each transplant 4 inches apart in rows or beds prepared with compost or aged manure.
Harvest Violet De Galmi onions after 105 to 110 days when the tops have dried and fallen over completely, a reliable indicator of bulb maturity. Gently loosen the soil around each bulb and pull when the papery outer skin feels dry. Allow harvested onions to cure in a cool, dry, well-ventilated space for 2 to 3 weeks before storing, which hardens the skin and extends storage life.
