Connecting the community to nature through a diverse and beautiful collection of historical gardens.

HSBG was created in 2000 using historically significant private gardens saved from demolition by the expansion of the SeaTac Int'l Airport's construction of their 3rd runway. Between these two full-featured collections lie an eye-catching series of beds sponsored by local garden enthusiasts, including the Puget Sound Daylily Club, the King County Iris Society, and the Seattle Rose Society.

Homecoming season looks good in the Garden! 🍂✨

We loved seeing students dressed up and making memories among the autumn colors. From the Rose Garden to our winding pathways, there's no shortage of picture-perfect backdrops for life's special moments.

Whether you're celebrating a milestone, gathering with friends, or just looking for a beautiful place to snap a few photos, the Garden is here for you.

📸 Have you taken photos at the Garden? Tag us! We'd love to see them.

Visit the Highline SeaTac Botanical Garden during the PNW's peak fall color display, this year predicted to be October 29-November 7, 2026 in South Seattle. As the intensely colored leaves begin to drop, notice the intricate, branching architecture of the many Japanese maple (Acer palmatum) specimens in the garden, particularly in and around the Seike Garden.

Some of the varieties pictured: Acer palmatum 'Manyo no sato', Acer palmatum 'Amber Ghost', Acer shirasawanum 'Palmatifolium'

Take yourself for a walk in the Garden with our self guided maple leaf ID and see how many Japanese maples you can identify. Visit this page on our website to download and print: https://highlinegarden.org/your-garden

Fall is for apple picking and the PNW season officially opens later this month! Next time you walk through the Highline SeaTac Botanical Garden, notice the tree netting work done by our volunteers and apple orchard managing partner . According to WA State University, the main benefit of protective tree netting is the improvement in fruit quality through sunburn reduction. Other benefits include a reduction in hail damage, wind damage, bird and insect pests, and an increase in water savings.

Please don't pick or eat the apples in our orchard–this fruit will be harvested and donated to local food banks and meal programs. Instead, visit these profiles to find out where you can pick apples in your area this month:

Visit the garden this month to see the Puget Sound Fuchsia Society Garden in full bloom. Enjoy multiple specimens exhibiting flowers ranging in size, color, and texture. These long blooming perennials work well in hanging baskets or containers and when planted in the ground can grow into large, easy to maintain shrubs.
