Stone bench next to mulch pathway in lush green garden with blooming pink echinacea in the background and salvia in the foregroundThe Pacific Northwest’s unique climate allows for an amazing gardening experience; our warm dry summers and mild winters support everything from desert plants to Japanese gardens, to thriving fruit and vegetable gardens.

We have incredibly diverse native plant life as well which provide food and habitat for our birds and pollinators, including hummingbirds, bees, moths, butterflies, and even bats. More than 600 species of native bees call Washington State home, none of which are the honey bee you may be most familiar with!
