Course Description

Enrich your understanding of our local natural areas by learning to identify the most common native plants you’re likely to encounter. Colorful flowers and swaying grasses change from day to day in the Arboretum’s prairies, woodlands, and wetlands. Take a morning stroll with an expert and learn to identify some of the stars of summer.  Great for the beginner or for any naturalist looking to brush up on native plant ID.

Instructor: Spencer Campbell, natural resources manager
Notes: Held mostly outdoors. Please dress for the weather and for walking in tall grass. Limit 20.
Supplies: Please bring your hat and water bottle and wear sun and insect protection. A hand lens and your favorite field guide will be useful (some will be available to borrow).
