Collards, Cascade Greasy

Collards, Cascade Greasy
(Brassica oleracea var. viridis)

Cascade Greasy Collards is a traditional Southern heirloom known for its smooth, glossy leaves and exceptional cold tolerance. Unlike crinkled collard varieties, its “greasy” leaves have a slick surface that sheds frost and resists damage. This variety produces tender, flavorful greens that improve in taste after exposure to cold weather, making it a dependable staple for fall and winter harvests.

Key Characteristics

• Smooth “Greasy” Leaves
  Leaves have a distinctive glossy, smooth surface rather than the typical crinkled texture. This trait helps shed frost and makes the leaves easier to clean and prepare.
• Rich Flavor that Improves with Cold
  Cascade Greasy develops a mild, slightly sweet flavor that becomes more pronounced after frost. Ideal for traditional slow cooking, sautéing, and hearty greens dishes.
• Exceptional Cold Hardiness
  Highly tolerant of cold temperatures and capable of overwintering in milder climates. Provides reliable greens well into late fall and winter.
• Productive & Long Harvest Window
  Plants produce abundant leaves over an extended period. Harvest outer leaves regularly to encourage continued growth.
