Introduction to Flowering Plant Identification: The Basics
Saturday, May 209am-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.
