"Sweet, tender leaves with excellent frost tolerance.
Voted the best-tasting in our taste tests, with blue green leaves and white ribs that get sweeter in cold weather. Tolerates wet soils and just as hardy as the toughest Russian. Bred by Frank Morton of Wild Garden Seeds and released through the Open Source Seed Initiative. B. napus.
Open Source Seed, Tolerates wet soil, Very cold-hardy, 24-30" tall."
