Certificate Programs

Our two certificate programs, Botanical Arts and Native Plants and Ecological Horticulture, are a great opportunity to learn new skills and nourish passions, whether for personal or professional growth. Graduates of the program(s) will earn a certificate awarded by the Gardens, which may be used as a marketable resume item, or simply as a statement of personal growth celebrating learning for learning’s sake.

Each program consists of 11 required courses and several elective workshops or trips. Students may progress through the curriculum at their own pace; a highly-motivated student can complete the program(s) over the course of nineteen months (two growing seasons). Instructors include a combination of on-staff and expert guest instructors with a variety of specialties. Courses are held on Gardens’ grounds in our LEED-Certified Bosarge Education Center, and in the field on the beautiful Boothbay Peninsula and beyond.

For more information, and for a full list of required courses, please see our informational fliers. If you have further questions, or to enroll, please contact Daniel Ungier, Director of Education, at (207) 633-8038 or dungier@mainegardens.org.

“I have so enjoyed all of the classes in the certificate program as well as the interesting and helpful electives… These classes have been not only enjoyable but life-changing for me. I still have sooo much to learn even though I’ve been gardening since I was three. CMBG is truly a botanical gem!” – 2017 Certificate Program graduate

Certificate in Botanical Arts

The beauty of gardens and plants inspire artistic expression in many forms. CMBG celebrates this broad palette of expression in our Certificate in the Botanical Arts program. Instructors from New England and beyond teach courses in several varieties of botanically-inspired arts, including book and paper arts, botanical and scientific illustration, plein air painting, fabric design, wood block printing, and more. Offerings are unique and ever-changing, but all incorporate our stunning gardens for subject study and inspiration.

There are two core classes required for graduation: Fundamentals of Botany, and Drawing and Painting with Katie Lee. Completion of the program depends on a final independent project overseen by a mentor. Final projects can be in any media with the approval from the Education Department. Development of a body of work and a thesis will consolidate the ideas and practices of each individual student. There is a fee associated with this project.

Certificate in Native Plants and Ecological Horticulture

The field-based Certificate in Native Plants and Ecological Horticulture program instructs both amateur and professional gardeners about Maine’s diverse flora and its uses in ecologically responsible horticulture. The program is tailored to Maine gardeners by featuring the climate conditions, specific challenges, plants, and natural communities found right here in the Pine Tree State.

Students benefit from engaging, hands-on courses describing native plants, how they function and reproduce, their natural habitats, and best garden applications. Optional workshops and field trips focusing on specific skills, such as seed collection and propagation, identification of wild plants, creating green roofs, methods of composting, etc., allow students to customize the program to suit their own interests.

To ensure a top-quality experience for participants, admission to the program is limited to only 15 new students per year. The full schedule of courses for the year is typically posted in January.

10 a.m. – 4:30 p.m.

The use of native herbaceous plants in a horticultural setting will be the topic of this combination classroom and in-garden workshop. Taking place over two days—once in the spring season (May 23) and then later in the growing season (July 11)—native plant expert Bill Cullina will introduce students to native plants to use in different horticultural settings, based on their habitat preferences in nature. Native plant selections for different combinations of soil pH, sun and shade, and wet and dry substrate will be considered. Selecting plants for aesthetic qualities such as color and texture as well as for broader ecosystem considerations will be discussed. Finally, learn about the use of native plants in niche garden communities, such as woodland or meadow gardens, and their role in ecological restoration.

Fundamentals of Botany

with Kyle Martin
Wednesday-Thursday, June 13-14
9:30 a.m. – 4:30 p.m.

In this course you’ll learn the core concepts of plant biology to help ground your appreciation for working with plants. We’ll cover the basic parts of a plant and how they work together to sustain the processes of photosynthesis, respiration, and water and mineral uptake. We’ll follow the biology of a flowering plant through its life cycle, from germination and seedling establishment to flowering, fruiting, and seed dispersal.

Through both explorations in the Gardens and in the classroom, students will achieve a whole new perspective on what goes on during the course of a plant’s life. The textbook required, Botany for Gardeners by Brian Capon, will be available for purchase from the Gardens on the first day of class.

Gardening for Wildlife

with Doug Tallamy
Friday, July 6
9:30 a.m. – 4 p.m.

Habitat loss is the number one cause of declining wildlife populations. In this class, learn why gardening for wildlife is as important as it is rewarding. Join biologist Doug Tallamy as he explains how, by incorporating certain native plants and gardening practices into your own landscape, you can create a welcoming habitat that attracts wildlife, conserves natural resources and encourages biodiversity. Both in-classroom instruction and forays into the Gardens will provide numerous examples for creating a lively (and lived-in) garden habitat.

Natural Communities of Maine

with Ted Elliman
Thursday and Friday, July 26 and 27
9:30 a.m. – 4 p.m.

A truly comprehensive understanding of Maine’s native plants necessitates an understanding of how native plants behave in their natural habitats. In this two-day introduction to the natural communities of Maine, ecologist Ted Elliman will acquaint students with several of Maine’s characteristic plant communities, their defining physical environments and the natural processes affecting them. Both in the classroom and in the field, students will learn the differences between community types such as salt marshes, red maple swamps, northern hardwood forests, bogs and floodplain forests. Discover some of the common plants occurring in these communities as well as what plant adaptations are key to competing successfully in each.

The primary reference for this course is Natural Landscapes of Maine: a Guide to Natural Communities and Ecosystems by Susan Gawler and Andrew Cutko. Bring a lunch, sturdy waterproof shoes and your sense of adventure.
