Beauty and Benefits

James Brown
Owner/Operator, New Moon Nursery

Rather than looking at plants that just provide beauty for humans, nurseryman James Brown will highlight some of his favorite native plants that provide a local food source for wildlife in addition to being beautiful. He will also share information on some of the early leaders and standouts in the pollinator trials and other happenings at New Moon Nursery. Be prepared to learn about some underutilized native gems!

Managing Maintenance

Rebecca McMackin
Director of Horticulture, Brooklyn Bridge Park

Brooklyn Bridge Park, and 85 acre, organic park in the middle of New York City, was created with ecology in mind. The park’s award-winning piers include top-notch recreation, from opera to outdoor films, expansive organic lawns, and fantastic food, all of it beautifully designed. In addition, the piers also contain native woodlands, freshwater wetlands, salt marshes and numerous meadows. These areas closely mimic native ecosystems and are managed with an emphasis on wildlife habitat. This talk will encompass the many ecological strategies employed by the park’s designers, as well as the management technology currently in use to cultivate biodiverse parkland. Pragmatic strategies for encouraging ecologically beneficial landscapes will be illustrated.

Untermyer Gardens: Past, Present, Potential

Tim Tilghman
Head Gardener, Untermyer Gardens Conservancy

The Untermyer Gardens Conservancy is a nonprofit organization that is collaborating with the City of Yonkers to facilitate the restoration of Samuel Untermyer’s garden in Yonkers, N.Y. In 1899 Samuel Untermyer purchased Greystone, the former estate of Samuel Tilden. In the 41 years that Untermyer owned Greystone, he transformed the gardens and greenhouses into one of the most celebrated gardens in America. The Untermyer Gardens Conservancy is currently working to restore the grandeur of this once world-renowned garden.

Lunch | 12:30 – 1:30 p.m.

Afternoon Sessions | 1:30 – 4:00 p.m.


Plants with Benefits

Melanie Ruckle
Owner,  Putnam Hill Nursery

Even though there are many new introductions of patented plants every year, Melanie Ruckle gravitates to exceptional plants that perhaps have been around for years, but have not been given the spotlight or have fallen off the public radar. An exceptional plant for Melanie must serve a purpose in the landscape, attract favorable wildlife and offer more than one season of interest. Often these plants are not as showy, but have long-staying power in the garden in a supporting role. Melanie will share her observations and discoveries made during her 28 years in the horticulture industry.

Plants with Style

Kelly Norris
Director of Horticulture, Greater Des Moines Botanical Garden

Gardeners need chic, sustainable, thriving plants for modern lifestyles. Why settle for lackluster gardens filled with dull, ho-hum plants? Plants after all are the very essence of fashionable gardening. In this spirited, provocative lecture, plantsman Kelly Norris calls for a garden revolution: out with boring plants and in with stylish alternatives that captivate and enthrall. A passionate horticulturist and lifelong gardener, Kelly is the ideal guide to the botanical riches available to today’s gardeners. He will share his A-list plants that will thrive, not merely survive, and show you how to forge a personal style in harmony with your garden’s setting and local environment.
