Radicchio Seeds – Non-GMO Heirloom

The bold, jewel-toned chicory worth a spot in your garden

Radicchio (Cichorium intybus) is a cool-season leaf chicory grown for its dense, colorful heads of crisp, pleasantly bitter leaves. Best known in its wine-red, white-veined forms such as the round Chioggia and the elongated Treviso, it brings striking color and a sophisticated bitter-sweet bite to the plate. As autumn cools, loose green rosettes tighten into firm, vivid heads, and a light frost actually sweetens the flavor. Handsome in the bed and versatile in the kitchen, radicchio is a favorite of adventurous gardeners.

How to grow radicchio from seed

Radicchio rewards good timing more than fussy care. Sow radicchio seeds about a quarter inch deep in full sun and fertile, moisture-retentive soil, typically in mid to late summer so heads mature in the cool of fall, then thin to stand eight to ten inches apart. Plants take roughly 60 to 90 days to head up, and cooling weather is what triggers them to color and firm. A light frost improves both sweetness and hue.

How to use radicchio

Radicchio is loved for its bold color and bitter-sweet bite. Shredded raw, it adds crunch, color, and a sophisticated edge to salads and slaws. Cooking transforms it: grill or roast the wedges and the bitterness mellows into deep, caramelized sweetness. It is a classic in Italian risotto and pasta, wilted with pancetta, or drizzled with good olive oil and balsamic. A little goes a long way toward brightening a plate.

Radicchio and its chicory and salad cousins

If you love radicchio, you will likely enjoy its chicory relatives and salad companions. Try endive for another crisp, bitter chicory, lettuce for tender salad heads, or arugula for a peppery leaf to balance the bitterness. You can explore the full range in our vegetable seeds collection.
