Description

Cabbage 'Radicchio' (Cichorium intybus var. foliosum), commonly known as Radicchio di Chioggia or Italian Red Cabbage Chicory, is a prized open-pollinated Italian heirloom celebrated for its vibrant coloration, crisp texture, and pleasantly bitter flavor profile. Growing into compact, tightly wrapped round heads roughly the size of a softball, it features deep ruby-red to magenta leaves laced with prominent, crisp white veins. Exposure to cool autumn weather intensifies both its striking coloration and natural sweetness. Indispensable in traditional Italian cuisine, Radicchio adds bold color, crunch, and sophisticated flavor to fresh salads, grilled dishes, roasted vegetable medleys, and risotto.
