Kale, Blue Curled Scotch
(Brassica oleracea var. acephala)

Blue Curled Scotch Kale is a traditional heirloom kale recognized for its tightly curled blue-green leaves and excellent cold tolerance. This hardy variety forms sturdy plants that produce abundant foliage throughout the cool season. With its rich flavor and reliable growth, Blue Curled Scotch has long been a staple in productive kitchen gardens.

Key Characteristics

• Tightly Curled Blue-Green Leaves
  Deeply ruffled leaves form dense clusters with a distinctive blue-green color. The curly texture adds visual interest and holds sauces and seasonings well in cooked dishes.
• Rich, Hearty Kale Flavor
  Leaves develop a full, savory kale taste that works especially well in soups, stews, sautéed greens, and roasted vegetable dishes.
• Excellent Cold Tolerance
  Blue Curled Scotch thrives in cool weather and becomes sweeter after exposure to frost. This resilience makes it well suited for fall gardens and extended harvests.
• Productive Upright Plants
  Plants grow upright and produce abundant leaves over a long harvest window. Harvest outer leaves regularly to encourage continuous growth.
