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