Chicory Rosa Isontina From the foothills of the Dolomites, tucked up against Slovenia in the northeast corner of Italy comes one of the most beautiful and celebrated of the chicories of the Friuli-Venizia Giulia. Late-summer sown, plants grow in the field through frost until the outer leaves begin to die back and are cut off and the roots are dug and brought in to force in darkness, or covered with a bucket to exclude light. The result is a delicate rose-shaped head of tender lightly bitter leaves.
Selection Cycles (days to maturity slots). For most vegetables growers stagger planting dates to provides a continuous harvest. With radicchio, a different strategy is employed. For most, heading radicchio is best suited to seeding around the summer solstice, Dec 21st to Jan 3rd, transplanting 3-4 weeks later. To achieve extended harvest periods, rather than staggering planting dates, radicchio uses days-to-maturity options within a type. These are often referred to as “slots” with many types having early, mid, and late slotted varieties
