Bill Cullina Wins the Edgar T. Wherry Award from NARGS “This is a really thoughtful and appreciated award," Cullina said. Bill Cullina, executive director of Morris Arboretum & Gardens, has won the Edgar T. Wherry Award from the North American Rock Garden Society. He received the award for outstanding contributions in the dissemination of information about native North American plants. Image “This is a really thoughtful and appreciated award, given that Wherry was such an important scientist and botanist here for many years,” Cullina said. Wherry (1885–1982) taught botany at the University of Pennsylvania from 1930 to 1955, and had a deep interest in ferns.

Prior to that he was the director of horticultural research for the New England Wild Flower Society (now Native Plant Trust) in Massachusetts.

While the native plant movement is currently in full swing, these three beautifully written and photographed books, which reside in the collections of many of us, were particularly valued resources on native plants in the days when such resources were few and far between. In addition to his writing, Bill shared his extensive knowledge of native plants through his many talks on these topics as well. He began his horticultural life at Garden in the Woods in Massachusetts, and gave many, many talks to the New England chapter, each packed with his careful observations of plants, and beautifully illustrated with slides. His talk on fern propagation was particularly memorable: He was showing a fertile fern frond under a microscope and …
