Description

Cabbage Premium Late Flat Dutch (Brassica oleracea var. capitata) is a legendary European heirloom introduced to North America in the 1840s, long prized as the gold standard for late-season harvests and winter cellar storage. Producing massive, broad, drumhead-shaped heads that can measure 12 inches across and weigh 10 to 15 pounds, it features smooth, dark blue-green outer leaves protecting a exceptionally dense, tight white interior core. Known for its mild, sweet flavor that grows even sweeter after autumn frosts, its high natural sugar content and dense texture make it the premier choice for homemade sauerkraut, bulk cabbage rolls, hearty stews, and long-term storage.

High frost tolerance—cool autumn temperatures improve leaf tenderness and sugar content

Long maturation time (~100 days) requires setting plants out early in the summer season
Broad spreading habit demands generous row spacing (24–36 inches) to allow heads room to swell
