Course Description

A backyard garden with a stone path running through it.

 Advanced Plant ID is a hands-on, in depth study of plants in the landscape.  Sections on leaf characteristics, floristics, winter twigs, ferns, ornamental grasses and weeds are included.  Expanding on the introductory course, this course discusses leaf tips, bases and margins; floral formulae and floral diagrams. A more concentrated study of botanical keys is made giving students the opportunity to create a formal key. Complex plants, including ferns, grasses and leafless twigs are discussed with a focus on key species in each group. Throughout the course, students will collect specimens, create a herbarium collection, and carry out physical assays and plant assessments along with many optional activities designed to support the course material. 

Designed For

This course is designed for everyone; home gardeners, landscape professionals, Master Gardeners and anyone else who wants a deeper understanding of plant taxonomy, systematics and identification.
