Deciding which poinsettia cultivars to grow is based on many factors and highly dependent on the market served. These recommendations are based on the cultivars' performance in our trials, other trial sites and commercial greenhouses. The National Poinsettia Trials evaluate new introductions and compare them to older varieties. Included in this list are newer varieties that show promise or offer characteristics not available in other cultivars, as well as established, older cultivars that are still important and make up most of commercial production. Not all available cultivars are on this list, and we have omitted some that were on previous lists.
