Seminar named in honor of the Copelands

The Copeland Native Plant Seminar was named in honor of the late Pamela C. and Lammot du Pont Copeland, noted philanthropists and conservationists. Along with the late Henry B. and Emily DuPont, the Copelands founded Red Clay Reservation, contributed funds for the original building at the Ashland Nature Center and provided land and resources for environmental education programs.

While supporting many worthy causes, the Copelands created one of the premier native woodland wildflower gardens in the country at their Mt. Cuba home on the rolling hills of the Piedmont in Northern Delaware. Later, their concern grew over the loss of the native species in the wild, they founded Mt. Cuba Center. Mrs. Copeland encouraged Delaware Nature Society to create the seminar and annual plant sale promoting the use of native species. This seminar recognizes the Copeland’s input in the growth and development of Delaware Nature Society plus their understanding of plants in a healthy ecosystem.
