Amaze your gardening friends with these huge flowers that can reach up to 8 inches across! And also with thick, sturdy stems, I think this one has been nipping the steroids. For a Dogwood, this is indeed a giant at 30'–40' tall. Its name was derived from the Columbia River Gorge (Col-ri-go) where it is endemic. A fast grower; shades of pink in fall.
Minimum temperature: -10° F
