Introduction to Flowering Plant Identification: The Basics

Saturday, May 20
9am-12pm
$15/HAF member, $20/non-member

Have you ever wondered how to identify native plants or common weeds? What characteristics should you look for, and how are plants sorted into groups? How are common and scientific names different?

This 3-hour workshop on the basics of plant identification will introduce novices and plant enthusiasts to the wonderful world of plant identification! We will learn about plant parts, leaf shape and arrangements, flower parts, fruit types, etc. and will also examine those key characteristics that place a plant into a certain taxon (named group). We will also have a brief overview of plant classification (naming), examine the notable features of five or six plant families, and introduce participants to a few local field guides that can be used in our region. No prior experience with plant identification is necessary!

We will also take a short walk in the arboretum to further look at plants and plant parts. Wear weather-appropriate clothing, comfortable walking shoes, and bring a small snack and water for our walk.

Note: This introductory workshop is designed for beginning plant identification enthusiasts. Those who seek to learn about using regional floras with specialized terminology and dichotomous keys should look for an upcoming advanced plant identification workshop. 

About the instructor: Dr. Mandy Tu is the Plant Taxonomist & Herbarium Curator at the Hoyt Arboretum. In this position, she is responsible for collecting voucher specimens and verifying the identity of the trees within the arboretum and is often asked to identify plants by natural area managers in the Portland region. She has a B.S. in Botany from the University of Washington and a Ph.D. in Plant Biology from the University of California at Davis. Mandy has taught many plant identification courses and workshops for botanical professionals and plant enthusiasts.

Limited to 15 people. $15/HAF member, $20/non-member. Registration is required. Sign up below via Paypal or call (503) 823-1649.
