Plant identification can be a challenge in the spring, as many plants are just beginning to emerge. In this half-day workshop, participants will head out onto the prairie at The Morton Arboretum to look at species that are in bloom in the spring. In addition, participants will learn to identify the early leaves and distinguishing features of plants that bloom later in the year.
This is an intermediate- to advanced-level program. Foundational plant identification knowledge and skills are required.
This program meets in person at the Arboretum.
