Our premier radicchio variety
Radicchio Chioggia, is the most widely available radicchio variety to the U.S. consumer. Chioggia has dark reddish-maroon leaves with white ribs and grows in a tight round head about the size of a grapefruit.
Radicchio plants are quite beautiful
Young plants are light green and leafy. As the tended plant matures a tight head forms in the center and turns a scarlet color creating a splendid two tone rose-like plant.
Superior Old-World Seed
Our superior seed was developed in Italy for size, color, and head density. Chioggia is available year-round. It is harvested fresh daily by Royal Rose in the Salinas Valley of California and seasonally in Arizona and Florida.

The versatile & mild radicchio
Treviso grows in an elongated head. Its leaves are similar to romaine lettuce or overgrown Belgian endive and are dark reddish-maroon with center white ribs. This milder form of radicchio is prized in salads. Its adaptability & shape makes it ideal for cooking and it is often grilled or baked.

A winter flower
Tardivo comes from the more common variety, Radicchio di Treviso that, after the first frost, is cultivated with a complicated growing-forcing-blanching-sprouting technique similar to the method that yields Belgium Endive. After the first frost, the radicchio is harvested leaving substantial taproot. Each plant is carefully freed of its outer frost-damaged leaves. These plants are then preserved in protected furrows where the taproot is immersed in spring water. It then forms new leaves in the absence of light. Tardivo is known as a Fiori d'Inverno or winter flower because it is only available from November to March.

The edible flower
Radicchio Castelfranco has a yellowish-cream leaf with red speckles. This beautiful, tender, lettuce-like ball unfolds like a rose. It is grown with the first frost. Delicate and fragile Castelfranco plants are harvested with a taproot and brought under a tented or roofed enclosure where they enjoy much humidity and little light. This radicchio is also known as a winter flower and is only available from November to March.
