Here’s an intriguing idea for the natural gardeners out there: take an online, free class to learn about Maryland native plants.

The instructor, Dr. Sara Tangren of the University of Maryland Extension Service, has created a class that you can do not only while the rain is pattering on your window, but that will carry you to nurseries and parks to learn more!

Learn about goldenrod, echinacea and blue sedge; ecoregions and native plant communities. Have you ever wondered what a cultivar is? You’ll find out and you’ll know how to use them.

There’s not even a test; you are just asked to go “mock shopping” and identify the difference between a “Lousy” plant and an ideal choice.
