Join us on Friday, April 6, to examine native plants and the significant role they play as smarter and more effective landscape plant options, replacing nonnative and invasive plants. In this class, proficient native plant growers and a plant biologist will pinpoint methods and conditions needed for successful landscaping with native plants, go beyond the traditional native plants listed in most catalogs, and give you more landscaping options for your clients. The class will delve deeper into the reasons surrounding the legislature’s recent ban on certain invasive plants so that horticulture and landscape practitioners can clearly communicate the issues at hand.

Common Gardening Misconceptions and the Reality Behind Them

with Justin Nichols
Saturday, June 16
9:30 a.m. – 12:30 p.m.
Shouldn’t we stake newly planted trees? What’s the deal with that pouch of miracle powder the garden center told me to put in the planting hole? My lawn service says it’s necessary to dethatch my lawn. My dad taught me to rototill the garden every spring.
Instructor Justin Nichols will cover the above topics as well as many more commonly-held beliefs about gardening, often based more on tradition or misinformation than on fact. We'll discuss what the scientific research shows, what landscape trade organizations hold to be the best practices on these matters, and where common sense comes into play. You are welcome to bring your skeptic’s hat, as class discussion is welcome. We will hold class primarily inside, but (weather permitting) we will spend some time in the living classroom of the Gardens.


Gardens for the Senses: An Intimate Garden Conversation with Tim Smit

with Tim Smit
Friday, June 22
noon – 3 p.m.

Join us the day after our Annual Garden Symposium for an exclusive and unforgettable lunch with Sir Tim Smit, co-founder of the multi-award winning Eden Project in Cornwall and ‘discoverer’ and restorer—along with John Nelson—of The Lost Gardens of Heligan, now one of the UK’s best-loved gardens. Enjoy an intimate group setting as Tim elaborates on themes covered in his Symposium lecture, including his vision for regenerating landscapes, human well-being, and the deeper meaning and purpose of placemaking. Following lunch, the group will tour the Lerner Garden of the Five Senses, then reconvene for tea and a final discussion. Register soon! Limited to 12 participants.


Slow Flowers

with Diane Walden
Wednesday, July 11
1 – 5 p.m.
Thanks to the extraordinary strides made in the national food and culinary scene in placing emphasis on local sourcing and organic choices, there has been a sea change in the way we eat—this is the “Slow Food” movement. Apply that same thinking to sourcing your flowers, and you arrive at the “Slow Flowers” movement: Where do our flowers come from? How are they grown?
Any gardener has an up-close-and-personal relationship with flowers. They are a source of wonder and constant change as bud turns to bloom turns to fruit or seed or drupe. This diverse class—part-lecture, part demonstration, and part hands-on work—will provide you with an opportunity to share some of Diane Walden’s floral harvest from the Gardens, to learn about the evolving “Slow Flower” movement, the state of the global flower market, our own Maine-grown local markets, and to create your own arrangement. Foraging, conditioning and design tips aplenty provided.


Day Trip to the Kennebunks: Snug Harbor Farm and Blackrock Farm

Thursday, July 19
10 a.m. – 3:30 p.m.
Join us for an experiential learning trip to visit two gems of Southern Maine: Snug Harbor Farm and Blackrock Farm. This pair of nurseries located in the Kennebunks are each unique, inspired by their owner’s visions and singular talents, and home to a loyal and dedicated following that stretches well beyond their region. At both locations, we’ll be treated to behind-the-scenes tours of the operations and have a chance to hear the story behind each business. At Snug Harbor Farm, we’ll also take part in a brief succulent-planting workshop, and each participant will be able to bring a small planting home with them. To top it all off, between visits we’ll dine for lunch at The Colony Hotel, a 1914 Kennebunkport landmark, well-recognized from both land and sea. Come join us for an unforgettable tour of some of Maine’s best-loved nurseries!
