Seasonal Highlights Your Clients Shouldn’t Miss
One of the Arboretum’s greatest strengths is its year-round appeal, with each season delivering its own unique experience. Knowing what’s in bloom when will help you guide your clients to the most spectacular areas during their visit.
Spring Spectaculars
Spring transforms the Arboretum into a riot of color. Azalea Way, a 3/4-mile path lined with cherry trees, azaleas, and dogwoods, erupts in pink and white blooms from March through May. This iconic pathway dates back to the 1930s and remains one of Seattle’s most photogenic springtime attractions.
The Rhododendron Glen also reaches its peak in spring, showcasing Seattle’s official flower in all its glory. With over 700 rhododendron species and hybrids throughout the Arboretum, visitors can witness an unparalleled display of these magnificent plants.
Summer Serenity
Summer brings lush greenery and the perfect opportunity to explore the Japanese Garden, a 3.5-acre formal garden requiring a separate admission fee ($8 for adults). This meticulously maintained garden features traditional elements like stone lanterns, bridges, and a tea house—perfect for clients seeking tranquility.
The Woodland Garden offers a cool respite on hot summer days, with its canopy of mature trees creating a peaceful oasis. The recently restored Waterfront Trail provides stunning views of Lake Washington and the Cascade Mountains, especially magical during sunrise or sunset.
Autumn Colors
Fall transforms the Arboretum into a painter’s palette of reds, oranges, and golds. The Japanese maples and sourwood trees create some of the most spectacular autumn displays in the Pacific Northwest. The Maple Collection features over 70 species, creating a fiery spectacle typically peaking in late October to early November.
- Japanese maples turn brilliant red and orange
- The Woodland Garden’s diverse trees create a mosaic of fall colors
- Fruits and berries appear throughout the collections, attracting local wildlife
- Fewer tourists make autumn an excellent time for a peaceful visit
Winter Wonders
Even in winter, the Arboretum offers unique beauty. The Winter Garden showcases plants specifically selected for their cold-weather appeal, with colorful bark, berries, and early-blooming winter flowers. The Joseph A. Witt Winter Garden, established in 1988, features fragrant winter-blooming shrubs like witch hazel and winter sweet that fill the air with unexpected perfume.
The bare branches of deciduous trees reveal architectural forms often missed in leafier seasons, while evergreens provide structure and greenery against the gray Seattle skies.
