About Redbor

Redbor is a hybrid curly kale with deep purple-red, frilly leaves and a habit similar to Winterbor. It combines ornamental color with solid cold hardiness and good bunching quality.

Growing Redbor Kale

Cool weather intensifies the color, so this variety is especially striking in fall plantings. Give it full sun for the best leaf color, and harvest outer leaves steadily to keep the center producing fresh growth.
