He pursued his education in hort iculture and botany at American River College and Sacramento State. Early work included mapping rare and endangered plants for the State of Californ ia as well as landscape and design work\, often revolving around his love of western natives.\nFrom the mid-80s to the mid-90s\, Sean worked as the curator of South African\, New Zealand\, Australian\, New World Desert and California Native Cultivar Gardens of the UC Berkeley Botanic Garden. In 1995\, he and his partner\, UC Davis Arboretum Botanist Parker Sanderson\, returned to Portland to start a design and consultation firm specializing in regionally appropriate plants for the Pacific Northwest. This eventual ly evolved into their opening Cistus Nursery\, located on Sauvie Island in the Columbia River west of Portland. Cistus Nursery is highly regarded as one of the best west coast retail nurseries and known worldwide for its c ollection of rare plants and advocacy of unusual and underused plants.\n\n Hogan has lectured extensively in North America and Europe in addition to explorations of South America\, South Africa and the western regions of th e United States and northern Mexico.

John studied ecol ogy and evolutionary biology at the University of Colorado at Boulder and received his MS in Horticulture from Colorado State University.  A life- long gardener\, his professional background is in public horticulture\, ha ving worked at regional public gardens for 10 years before joining Extensi on.  John is particularly interested in the creation of low-maintenance\ , high-impact landscapes in difficult places\, and loves using rock garden s to solve landscape issue\n\n \;\n\nReserve your seats while they las t!\nMembers:\nIf you do not see “Howdy” followed by your name in the u pper right-hand corner\, you are not logged in.
