Red Russian/Siberian Kale: Sweeter than traditional varieties

This rare kale variety has red-purple veins on slate-green, wavy-margined leaves. Cool weather intensifies its color.

The grey-green leaves turn purple in cold weather. This delicious grey-green kale is pretty enough to plant among the flowers. It is much larger than regular kale (2 to 3' tall), the stems are purplish and the leaves are shaped like big oak leaves and colored a velvety gray green. The purple colors become richer after frost, when the flavor becomes sweeter. Surprisingly, the big leaves are very tender and delicious. Plants may be left outdoors all winter. Frost improves flavor
