The annual tradition, where specialty growers give fun presentations on interesting and unusual plants, will take place at 2 p.m. Sunday, March 5 at Lake Oswego High School Auditorium, 2501 Country Club Road, Lake Oswego, Oregon. Doors will open at 1 p.m. and those interested should line up ahead of time to be assured of a seat. The auditorium seats 640. That’s a little more than the prior venue, which seated 500 and was always full. Admission is free. Participants get a goody bag that includes a FREE Retail Nurseries and Garden Centers Map, courtesy of Plant Something Oregon and the Oregon Association of Nurseries.
