Product Overview
Redbor Purple Kale stands out with its striking deep purple-red foliage and tightly curled leaves. The texture is both sturdy and tender, offering a rich, earthy flavor with a subtle sweetness that performs beautifully in cooked dishes or raw preparations. This variety is exceptionally cold tolerant and often becomes even sweeter after exposure to frost. The plants grow with consistent vigor, supplying leaves steadily through the season. Suitable for larger beds or roomy containers, Redbor adds dramatic color along with nutrient-dense, highly versatile greens—making it as ornamental as it is productive.
