Grow crisp, mild white onions with White Grano Onion Seeds from Survival Garden Seeds. This classic short-day variety produces smooth, white bulbs averaging about 3 inches in diameter and is known for its low pungency and versatile flavor. White Grano performs especially well in southern and western regions, including Texas, and offers dependable growth with the added benefit of being slow to bolt.
Mild, Versatile Flavor:
White Grano onions deliver a clean, gentle onion taste that works well in a wide range of dishes. Their juiciness and mild character make them excellent for raw uses such as salads, salsas, and sandwiches, while also shining in cooked recipes where a balanced onion flavor is desired.
Short-Day Onion for Southern Gardens:
Adapted to regions with shorter winter days, White Grano forms bulbs reliably when grown in southern climates. Its slow-bolting habit allows for a longer harvest window and short-term storage compared to many other short-day types. Gardeners appreciate its consistent sizing, steady growth, and dependable yields.
Why Customers Love White Grano Onion:
- Mild, low-pungency flavor suitable for raw and cooked dishes
- Produces uniform 3-inch white bulbs
- Short-day variety ideal for southern and western growers
- Slow to bolt for a longer harvest period
- Versatile in the kitchen and easy to grow
How to Grow:
Start seeds indoors 8–10 weeks before your intended planting date, or sow directly outdoors in suitable climates. Transplant into loose, well-drained soil in full sun. White Grano forms bulbs when grown under short-day conditions, making southern regions ideal for this variety. Keep soil evenly moist, weed regularly, and harvest when bulbs reach full size and tops begin to fall. Use promptly or store short-term in a cool, dry place.
