Summary
Coreopsis, commonly known as tickseed, is one of the most popular, best-selling perennials available today. Numerous cultivars are available in a wide array of colors and habits. However, there is a great deal of confusion among gardeners because some perennial cultivars do not perform as well as advertised. They may be short-lived perennials, or in fact, act like annuals. Sadly, many are also prone to pests and disease. In addition to the uncertainty surrounding their long-term performance, there are also several species of coreopsis which have thus far been overlooked by horticulture. After evaluating the garden performance of these plants for three years, Mt. Cuba Center has produced recommendations for the selections best-suited to the mid-Atlantic region.
Below are detailed descriptions about the performance of each plant in the evaluation as well as a link to the Report that summarizes the important horticultural and ecological information about Coreopsis.
