Arboretum Autumn Walks

These three (3) Thursday morning walks led by Arboretum Education Director Garrett Brenden will go over the seasonal changes and highlights of the collection as we move out of the hot, sunny summer and into our cooler, wetter fall.

The walks will be informal, showcasing the changes and unique finds while we're out on the trails with each outing having a different theme to guide part of the discussion.

You can register for any singular walk or register for all three. The walks are free to the public, though there is a suggested donation of $5 per individual, per walk. Be sure to dress for the weather and the trail!

Free Native Plant Identification Public Workshops

Wednesdays, October 11, November 8

6:00pm to 7:30pm

Whether it's learning about grasses, identifying leafless twigs, or spending an evening determining which type of native aster we have in our hands, it's always a fun journey to learn together with the Washington Native Plant Society using the dichotomous keys at the workshops.

These are not formal "classes" but are more like a nature study club that likes to brush up on their flora of the inland northwest in different ways using real samples. Registration is preferred but walk-ins are welcome, though space may be limited.
