The Mt. Cuba Center TOP PERFORMERS Program was created based on the research of Mt. Cuba Center in Hockessin, DE. Each of the plants in this program received a rating of 4.0 or higher in their trials (on a scale of 1-5, with 5 being the highest).

The Mt. Cuba Center research team uses the Trial Garden to evaluate native plants and related cultivars for horticultural and ecological value, and to highlight the ecosystem services native plants provide. Our partnership with Mt. Cuba will help to ensure that some of these great garden plants continue to be sold in the trade.
