Native Plants: in the Garden and in the Wild - Linda Hardison

What constitutes a native plant for gardeners in the Portland metro region? Native to North America? The Pacific Northwest? Or a Douglas Fir forest on Mount Hood?  Or the banks of the Clackamas River?  Linda Hardison, director of the Oregon Flora Project (OFP), is uniquely qualified to speak on this and offer advice on the use native plants in our gardens. 

Linda believes calling a plant “native” requires consideration of both time and place.  Speaking from the perspective of the OFP, she will introduce us to a myriad of Oregon’s native plants – along with naturalized and exotic species.  Together we will learn the context from which these plants arise and gain an appreciation for the biodiversity found in our state.

Linda Hardison has been director of the Oregon Flora Project since 2005. The OFP houses the Oregon Plant Atlas which consists of more than 540,000 records of plant distribution in Oregon. Its extensive photo gallery is a valuable resource for identifying native plants.  Linda is instrumental in the recent publication of Volume 1 of Flora of Oregon, a three-volume reference about the plants of our state.  Linda earned a Ph.D. in botany from the University of Washington and is a research assistant professor in the Botany & Plant Pathology Department at Oregon State University.
