Tower Hill Botanic Garden


Saturday, April 23, 10:00 am – 4:00 pm – Opening Day: Uprooted, Land Art by W. Gary Smith

This nature-inspired exhibition at The New England Botanic Garden at Tower Hill imagined by author, artist, and landscape architect W. Gary Smith features stunning sculptures among the landscape of Tower Hill. Made from natural materials collected at the Garden, this exhibit celebrates the connections between people and nature, combining art and horticulture to explore ecological design and artistic abstraction. Join us throughout the year for events, tours, drop-in activities, and more as we explore different ways to connect with the land through art. The show runs through November 1, 2022.

Gary Smith’s mission is to connect people with nature in innovative and unconventional ways. An award-winning landscape architect, his garden design work has focused almost entirely on public botanical gardens including the Lady Bird Johnson Wildflower Center, the Daniel Stowe Botanical Garden, Longwood Gardens, and the Santa Fe Botanical Garden. Along with Ryan Associates of Waltham, MA, he designed The Ramble here at Tower Hill Botanic Garden. In addition to his award-winning work in landscape architecture, Gary is also well known as an environmental artist. His temporary installations, a form of Land Art, have been installed in many public gardens including the Pittsburgh Botanical Garden, Filoli Historic House and Garden, Garvan Woodland Garden, Ganna Walska Lotusland – and more locally, Garden in the Woods. 

Join us for the opening of Uprooted on Saturday, April 23, and see Tower Hill’s grounds transformed by unique, magical nature-inspired sculptures. Enjoy nature inspired sculptures, drop-in programs, the family exploration station, and guided tours.

Saturday, February 26, 10:30 am – 12:00 noon – Basics of Orchid Growing and Repotting

Orchids are a beautiful plant that have so many flower varieties. Many of us love these plants but often have difficulty take care of them. In this Tower Hill Botanic Garden orchid workshop on February 26 from 10:30 – noon, Daryl Yerdon will start with the basics of orchid care with an emphasis on repotting. Together you will focus on the importance of proper pot selection and using the correct growing media for your type of orchid or your particular growing conditions. Daryl will also talk about how to water, fertilize and care for your orchids. At the end of the talk Daryl will demonstrate how to repot an orchid and leave time to answer any questions you may have.

In 1996 Daryl Yerdon joined the New Hampshire Orchid Society and purchased his first orchid at the annual show in Nashua, NH. Daryl’s orchid collection has grown from that first orchid to over 500 plants grown in a large greenhouse. In 2009 the New Hampshire Orchid Society awarded Daryl with the Sawyer Family Advanced Grower Trophy recognizing him as an expert grower for the NHOS. Daryl frequently displays his orchids at many local orchid society shows, where several of his plants have received a variety of awards from the American Orchid Society. From 2010 until 2021 Daryl was the owner of Kelley’s Korner Orchid Supplies which was recently sold to a new owner and relocated to Pennsylvania. Daryl grows a wide range of orchids in an 18′ x 28′ Arcadia greenhouse. Based on trial and error his collection has changed throughout the years. At this time the majority of plants are primarily species orchids but with a nice selection of favorite hybrids mixed in. The largest genus in his collection would be dendrobiums, but he grows a wide variety of orchids in pots as well as mounted on various materials. Daryl plans continue growing orchids, displaying them at orchid shows and becoming more active at the Massachusetts and New Hampshire Orchid Society meetings where he can provide his knowledge and expertise to other growers.

Wednesdays, February 2 – February 23, 6:30 pm – 7:30 pm – Ecology Lecture Series: Invasive and Non-Invasive Plants, Online

Join the Berkshire Botanical Garden for all four lectures in our ecology lecture series presented in partnership with Tower Hill Botanic Garden. Please note, all lectures are offered online and it is possible to register for individual lectures. The talks will take place Wednesdays, February 2 – 23 from 6:30 – 7:30 pm.

On February 2, the topic is Iconic Birds of Massachusetts and their Habitat. With a wide range of available habitats, Massachusetts is home to a fascinating array of birds. Join an experienced naturalist from Mass Audubon for an engaging talk about the noteworthy birds of Massachusetts and their incredible life histories. From migration to surviving the cold winters, we will explore the brilliance and challenges of our northeastern birds. This talk will include a captivating slideshow and discussion from a life-long naturalist with a passion for birds. Learn more about these avian friends and where to find them.

February 9 brings Building Healthy Soil in Harmony with Nature. Soil in many ways is the bedrock of successful environmental systems. Without good, healthy soil, these systems can collapse. Despite the importance of soil, we often don’t take the time to understand how it works, how we can cause it harm, and ways we can improve it. In this webinar we will explore the science of soil, learn what healthy soil is composed of and how it is created, and discover ways to prevent damaging soil. By the end you will begin to see how gardening in harmony with nature can build healthy soil, healthy plants, and rich ecosystems. Lecturer Duncan Himmelman, PhD, is the former Education Manager at Mt. Cuba Center, a consultant on garden design and plant selection, and a frequent lecturer on many horticultural topics. After earning his doctorate in Ornamental Horticulture from Cornell University and serving on the faculty of Olds College for 24 years, Duncan remains committed to nurturing the talents of people who share his love of plants, nature, and gardening.

February 16 is the date of Invasive and Non-Native Plants with Mark Richardson. A common topic when discussing habitat health is invasive and non-native species. Many of us know some species that we would refer to as invasive or non-native. Many of us have also been told how to think about or manage those species. However, rarely do we discuss what makes a plant invasive or non-native, if that criteria changed, what the data is currently showing about their presence if management practices adjusted with more data, and how climate change is impacting our view of invasive and non-native plants. These are just a few of the questions we should be asking. This lecture will discuss what classifies a plant as invasive or non-native and introduce some of those questions about a subject that touches all of our lives. 

Mark Richardson has been the Director of Horticulture for Tower Hill Botanic Garden since 2018. He previously served as Botanic Garden Director for New England Wild Flower Society, where he oversaw Garden in the Woods and Nasami Farm native plant nursery. He has a passion for ecological horticulture and native plants and is co-author of Native Plants for New England Gardens (Globe Pequot, 2018).

The final talk on February 23 is Wildflowers of Massachusetts. This program will feature the native wildflowers of a variety of natural habitats in Massachusetts, including forests, meadows, and wetlands. The emphasis will be on the early-blooming ephemeral wildflowers that will be in bloom in late April and May …something to anticipate in the depths of winter! 

Ted Elliman worked for many years for Native Plant Trust as a staff botanist, invasive species program manager, and instructor of botany, ecology, and conservation classes. His book, The Wildflowers of New England, an identification guide to the region’s native flora, was published in 2016 by Timber Press. In the 1980’s, Ted started and directed an environmental education and wilderness adventure center in the Berkshires. Since the mid-1990’s, he has periodically led natural history tours to southwest China, where he worked for two years as a teacher and forest ecologist.

The Heirloom Gardener is a book for gardeners who want to deepen their knowledge and improve life for families, pollinators and wildlife in their own backyards. It’s a love poem to the earth; a map to the art of living intentionally and a guidepost for environmental gardeners and artisans. It unearths old-ways, storied plants and artisanal life-skills; like seed-saving, herbalism, foraging, distillation, ethnobotany and organics which contribute to a new 21st century arts and crafts movement. With woodcuts from Caldecott Medal artist Mary Azarian, The Heirloom Garden offers a dose of wild hope for a weary nation.

Signed copies of the book are available through Tower Hill’s Garden Shop. You can shop online or stop into the garden and grab it in person.

As a Slow Food USA Governor and biodiversity specialist, his preservation work has helped to restore countless native and heirloom plants and has brought traditional artisanal practices to modern thinking. He has won numerous awards for historic garden preservation, children’s garden design, herbal and historical education and the 2021 Award of Excellence from National Garden Clubs, the largest volunteer gardening organization in the world. This book was inspired by his posts as ‘The Heirloom Gardener – John Forti‘ which go out regularly to millions on Facebook that value his uniquely curated blend of history, horticulture, environmentalism, poetry, art, kitchen and garden craft. He gardens and lives along the banks of the Piscataqua River in Maine.

Saturday, October 30, 10:30 am – 12:00 noon – Growing Cacti and Succulents in New England

Cacti and Succulents thrive in desert locations all over the world. Growing them in New England can pose quite a few problems for these arid loving plants. In this October 30 Tower Hill Botanic Garden class we will discuss the ways that we can help our cacti and succulents acclimate to living in the northeast. Too much water, not enough sun, too organic soil, these are all big problems for cacti and succulents. But, with the right horticultural knowledge they can all be easily solved. We’ll also go over propagation, containers, where to buy, and local resources for all things cacti and succulent related. Feel free to bring any plants that you have questions about as well.
