Sean’s objective is to popularize the unlimited joys of the plant world through education, outreach, example, and contagious enthusiasm. Currently, his focus has been on the introduction of new and appropriate plants to Western North America, and specifically, the popularization of under-used and unknown plants for summer-dry climates.
Sean served as the Director of Collections at the Hoyt Arboretum and a Horticulturist at the University of California Berkeley Botanical Garden strengthening existing collections, designing new collections, and drawing larger audiences to the gardens.
Sean is the owner of Cistus Design Nursery, a small firm specializing in public and private garden design, planning, public space planting design, nursery consultation, and the collection and introduction of new and appropriate plants. With over ten thousand taxa on site, Cistus furthers a nearly two-decade-long commitment to testing plant performance in the Portland area and providing interesting and unusual, climate-appropriate plants for the Pacific Northwest, the West, and beyond. Through extensive speaking and plant-collecting throughout the world, Sean continues to exchange his knowledge with diverse communities.
