The last three gardens on last Saturday's tour included a large shade garden, a tropical oasis and an Asian-inspired retreat. First, the Hilderbrand garden in Oregon City. This garden is set in a grove of Douglas Fir trees and has paved pathways that meander through plantings of dogwoods, hydrangeas, viburnums, kalmias and other shade-loving plants.  The garden of Michael Hicks and Megan Big John is a quarter-acre plot in West Linn. This garden is packed with plantings of tropical plants with big beautiful leaves and vibrant pops of color. Helena Wagner's "4 Seasons Garden" is a garden that I have visited in the past. It features an Asian-inspired theme with beautifully placed plants, with nice colors and contrasts. Text and photos by Phillip Oliver, Dirt Therapy
