What Winter Radish Round Black is

Winter Radish Round Black (Raphanus sativus var. niger) is an annual vegetable of the Cabbage family (Brassicaceae). This is a black winter radish variety. The black skin of this radish contrasts beautifully with its pure white flesh.

It also has a pleasing spicy flavour that adds to winter salads and vegetable platters.

They store equally well in the ground or in the cellar.

The oil in radishes strengthens the immune system in winter, which is why they are often eaten raw and salted, or cooked as an ingredient in soup.

Winter radishes (black, white and purple radish) are sown in summer and produce large, pungent roots that keep through the winter.
