The OPGC's focus on Coreopsis for 2013 was featured in an article about this genus that appeared in the March/April 2013 issue of the OFA Bulletin, the official publication of the Association of Horticulture Professionals. The article describes the diversity found in Coreopsis, focusing on the development of the many new colorful cultivars developed by interspecific hybridization. This native North American genus has seen a rapid expansion of new cultivars over the last 10 years highlighting the genetic diversity that can be exploited to develop new products. While the color variation is highly welcomed, there is still ample opportunity to enhancing the winter hardiness and disease resistance of this showy genus. The OPGC's germplasm collection of Coreopsis is intended to provide the genetic resources that may make further improvement possible.
