Classic Italian Heirloom Radicchio with Deep Red Leaves & Sweet Cold-Weather Flavor
Early Treviso Radicchio is a beloved Italian heirloom known for its elegant upright shape, striking crimson color, and complex, slightly bitter-sweet flavor that shines in salads, grilling, and braising. Closely related to the traditional Treviso varieties grown throughout Italy, this open-pollinated radicchio is especially prized for its early maturity and cold-weather performance.
Plants begin with mottled green leaves in warm conditions, then transform into sensuous deep red heads with bright white midribs and veins as temperatures cool. Harvested after frost, the flavor becomes noticeably sweeter and more refined.
Early Treviso grows compact and upright, making it well-suited for garden beds, raised beds, or containers. It’s weather-resistant and easy to grow, making it a great choice for both experienced gardeners and adventurous beginners. Many gardeners enjoy pairing it ornamentally with fall flowers or spring bulbs like tulips.
