Brassica oleracea medullosa

Botanical Description

Marrow-stem kale is a biennial plant derived in cultivation from the wild cabbage. It grows around 100cm tall. Marrow-stem kales are harvested for their edible leaves, which can be available even in the coldest of winters. The plant has fallen out of favour somewhat, and is not often cultivated for its edible leaves since these are coarser than other types of kale, and also coarser than other vegetables that can be imported from warmer areas in the winter.
