Notes
'Red Rock' onion (Allium cepa 'Red Rock') 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. Deer and rabbits usually look elsewhere for a meal. Plan on about 165 days to maturity.
Pairs well with Habanero habanero pepper, Berggarten sage, and Straight-8 cucumber.
