Kale Seeds – Willems Blue Groninger, ORGANIC

Brassica napus

HEIRLOOM. ORGANIC. This seedstock came to us from Experimental Farm Network, who received it from seedsaver Willem van Leeuwen of Pennsylvania. Willem’s Blue Groninger kale originated in Groningen, The Netherlands, and Willems strain has overwintered uncovered in PA, so we know it has truly exceptional cold-hardiness! Leaves are green with purple splashes and purple veining, with serrated edges similar to Red Russian kale.
