Rediscovering Forgotten and Heirloom Bulbs for Summer Gardens and Containers

Join plantsman Matt Mattus, author of the popular blog GrowingwithPlants.com, as he shares one of his greatest passions: rare and unusual bulbs. Mattus, known for his visually stunning and entertaining talks, promises to change how we think about the oft-neglected summer bulbs and excite us about some forgotten heirlooms as well. Learn about secret sources for everything from Achimenes (Hot Water Plant) to Zephyranthes (Rain Lilies) and a few other bulbs you may have never thought about either growing in pots or in the garden. Book sale and signing for Matt’s just-published Mastering the Art of Vegetable Gardening to follow.

Matt Mattus is an American plantsman, writer and journalist who can trace his horticultural roots back to elementary school days when he started experimenting with plant breeding—growing flowers and vegetables for shows at the Worcester County Horticultural Society, of which he is now vice president. Matt is the author of the popular and award-winning blog GrowingwithPlants.com and his gardens have been featured in Martha Stewart Living, Better Homes and Gardens and House Beautiful. He is past president of the North American Rock Garden Society, past editor of the American Primrose Society Journal, and founder of the New England Dahlia Society. His latest book, Mastering the Art of Vegetable Gardening (Jan2019) examines both common and uncommon vegetables worthy for the home gardener. Rich in cultural tips and professional advice, the book is a visual gem with hundreds of photos taken by the author. Matt lives in Worcester, Mass. with his partner Joseph Philip, three Irish Terriers, rare poultry, fancy canaries and homing pigeons. He sits on the board of the Tower Hill Botanic Garden in Boyleston, MA and currently works as horticulturist for the Boston-based firm, Landscape Collaborative, LLC.

The Natural History of Spring Wildflowers: A Closer Look

Besides adding beauty to our woodlands and gardens, native spring wildflowers play an important role in the ecology of our eastern forests. Carol Gracie, author of Spring Wildflowers of the Northeast: A Natural History, will show how these plants have adapted to their shaded environment and discuss their methods of propagation and dispersal and their uses as medicines, foods and dyes.

Carol Gracie is retired from The New York Botanical Garden, where she was Director of the Foreign Tour Program and the Children’s Education Department. She later worked in the Science Division, making dozens of trips to South and Central America, both as a tour leader and on botanical collecting expeditions. Her work has resulted in the naming of seven newly discovered tropical plant species and one new genus for her (including two named jointly for both Carol and her husband). She is a co-author, with her tropical botanist-husband, Scott Mori, of the two-volume Guide to the Vascular Plants of Central French Guiana. Carol has since returned to her earlier interest in local flora and is the photographer and co-author, with Steve Clemants, of Wildflowers in the Field and Forest: A Field Guide to the Northeastern United States (Oxford University Press, 2006). Princeton University Press published her latest book, Spring Wildflowers of the Northeast: A Natural History, in 2012. Carol is currently working on a book about the natural history of summer wildflowers.

Making a Great Garden Again! Paths, fountains, art and water with a healthy smattering of plants well-suited to our climate.

Join Longwood horticulturist, Karl Gercens as he traverses the globe in search of garden inspiration that works to make any garden great again! We’ll look at hardscape that is both functional and beautiful while softening the edges with leaves and flowers that truly pop in any situation. Whether it’s wet/dry or sunny/shady, there’s a plant for there and you can bet it’ll be beautiful with a minimum of effort.

Karl Gercens has been part of the team making inspirational displays in Longwood’s conservatory for over 20 years now. Millions of people take home ideas of color combinations as well as texture and form that work in their spaces. Originally from a cotton plantation in the Mississippi Delta, Karl has worked at Walt Disney World in Florida as well as Filoli Estate in California. From these diverse work experiences, Karl has developed his passion for colored foliage trees, shrubs and perennials for all spaces he cultivates. Garden design is consistent around the world and Karl has visited over 3,000 gardens in 30 countries to bring that inspiration back to his areas of responsibility at Longwood. In addition to sharing these ideas in classes and lectures locally, Karl has lectured at flower shows, plant societies and other public gardens as far away as Australia! 


6:30 to 7:15 p.m.
Bring donations of used or new garden tools to the Vollmer Center before the May lecture. Tools go to “tool libraries” for loan to community garden groups.
