Winter Radish Long Black

Winter Radish Long Black: variety and characteristics

Winter Radish Long Black (Raphanus sativus var. niger) is an annual vegetable of the Cabbage family (Brassicaceae). Winter-hardy, this variety produces long, well-formed cylindrical radishes. They can reach 20 cm. in length.

They mature when the days are shorter, the sunlight weaker and the temperatures milder.

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.
