This winter-hardy heirloom is a distinctive black colour on the outside with a milky white and tender interior that packs a bit of bite. Large turnip-shaped 8-10cm (3-4") diameter globes with deep black skins over solid, crisp, pungent, pure-white flesh. Black Spanish Round radish seeds have very tall tops, and are primarily grown for winter storage. They will stay fresh all winter if stored wet sand. This variety was introduced before 1824, and is listed in some old seed catalogues as Noir Gros Rond d'Hiver. Plant Black Spanish Round radish seeds in mid to late summer and eat when it is the size of a quarter. Space radishes 8-10cm (3-4") apart.
