Notes
'White Castle' onion (Allium cepa 'White Castle') is a vegetable for food gardens, containers, and borders. It is typically grown as an annual. It ranks among the more cold-hardy crops, and with some winter protection it keeps growing through light freezes. This plant likes full sun and dry to moist, sandy, loamy, or chalky soil. It needs 160 days to reach maturity, so plant early. Deer and rabbits rarely make it their first choice.
Pairs well with Spaghetti Squash, Salad burnet, and Fennel.
