Advanced Spring Prairie Plant Identification (in person)

Learn to identify prairie plants in their early stages of seasonal development.

Content Detail

Learn to identify prairie plants in their early stages of seasonal development. Plant identification can be a challenge in the spring, as many plants are just beginning to emerge. In this half-day workshop, we will head out onto the prairie to look at species that are in bloom in the spring as well as the early leaves and identifying features of plants that bloom later in the year.

COVID-19 Precautions: Program participants must abide by the Arboretum’s safety guidelines
