The annual Yard, Garden & Patio Show is expanding.
"In terms of sheer garden space alone, this will be the biggest show we've held to date," said Allan Niemi, events director for the Oregon Association of Nurseries.
The 2011 show, scheduled Feb. 18-20 at the Oregon Convention Center, will include seven display gardens covering 18,000 square feet, a 20 percent increase over last year, and 11 garden vignettes.
In all, the show will include more than 250 exhibitors and 23,000 square feet of gardens.
The 2011 show also will feature 45 hours of free seminars. The show's guest speaker is award-winning horticulture and gardening author Amy Stewart. Stewart has several books on the New York Times nonfiction bestsellers list.
The Oregon Convention Center is at 777 NE Martin Luther King Jr. Blvd., in Portland.
