Radicchio (Cichorium intybus var. latifolium) is grown widely throughout Europe, especially northern Italy. In addition to having interesting color and flavor profiles, they are rich in phenolics and other bioactive compounds. While increasingly popular as a niche vegetable in the region, there is little research-based information to guide growers. The New England growing climate is very different from that of major production regions, and it presents unique challenges. There is tremendous phenotypic variation among and within groups and cultivars. The availability of varieties to commercial growers in the U.S. has expanded greatly, but there remains a need for reliable regionally relevant information about performance of these varieties. In 2022 and 2023, we evaluated over 30 varieties in a replicated trial. We also planted three varieties at four different dates to evaluate the effects of planting date on harvest maturity and marketable yields. In the current research report, we describe the results of these experiments.
