Going Deeper

Coastal Maine Botanical Gardens offers opportunities for inspiration, discovery, and the study of a broad range of botanical and gardening topics. Our courses are taught by CMBG staff and regionally or nationally renowned experts in the field. Thanks to an average class size of 12-15 participants, students learn in an intimate environment where quality time with the instructor is the norm in the outdoor, living classroom of the Gardens.

Two certificate programs, the Certificate in Native Plants and Ecological Horticulture and the Certificate in Botanical Arts, anchor our annual course offerings. Each certificate program is comprised of a suite of required courses and a number of electives.

We believe in gardening and plant care for many reasons – beyond simply creating beauty, engaging actively with nature is key to a healthy life. Our Therapeutic Horticulture program provides opportunities for people of all ages and abilities to engage in therapeutic gardening practices.

Finally, our Advanced Studies in Professional Horticulture curriculum is designed for professionals working in the field of horticulture and landscape design. These courses keep active practitioners at the top of their game while advancing sustainability in their work.

Wherever you are in your botanical journey, there’s something to discover in our educational programming. If you don’t see something you’re looking for – let us know. We always look forward to the next discovery.
