The Winterjewel F1 hybrid belongs to the crop Brassica oleracea L. (White Cabbage Group) and is intended for winter production of greens. Public sources lack detailed data on maturity group, plant height, or specific indicators of resistance to diseases or lodging.
When searching for information about this variety, it should be noted that the trade name «Winterjewel» is also used for some varieties of ornamental garden roses, which can lead to confusion when identifying the plant.
