2017 Members’ Tour Day Theme Tours
TOUR A: The Arboretum’s A-Team: Around About the Acer Collection
Michael Dosmann, Keeper of the Living Collections
Maples make New England autumns brilliant. The Arboretum shares the foliar fireworks of the genus with more than 160 maple species from around the world. This tour explored some of the common as well as rare species, including their horticultural virtues and their natural history.
TOUR B: The World of Plants
Robert Dowell, Living Collections Fellow
Over many years of expeditions and exchanges, the Arnold Arboretum has amassed a fascinating, global collection of plants. Perhaps the best example of this geographic diversity occurs in the Bradley Rosaceous Collection, with plants from North America, Europe, Asia, and Africa. This tour explored this collection and the origins of its plants.
TOUR C: Beneficial Insects in the Dana Greenhouses
Tiffany Enzenbacher, Manager of Plant Production
Beneficial insects are an important component of the Arboretum’s integrated pest management (IPM) program, and they are increasingly utilized in horticulture as growers embrace more sustainable methods of pest control. Tiffany Enzenbacher shared how we use beneficial insects at the Dana Greenhouses, and how participants can use them in their own landscapes.
TOUR D: Zoochory
Brendan Keegan, Gardener
Zoochory, the distribution of seeds by animals, is the primary mechanism of seed dispersal by trees worldwide. Some examples of zoochory, such as squirrels caching acorns and accidentally spreading oaks, are readily observable; others, such as the role extinct megafauna may have played in spreading osage orange, are less so. Brendan Keegan led a tour explaining some of the plant-animal relationships among the trees in our collection.
TOUR E: CANCELLED
TOUR F: Exploring the Explorers Garden
Matt McDermitt, Curatorial Assistant
The balmy microclimate of the Explorers Garden displays some of the harder-to-establish wild-collected plants in our collection. With specimens gathered from around the globe over the past century, this spot showcases the Arboretum’s historic legacy of plant collecting. Matt McDermitt shared highlights, including plants from the panhandle of Florida to the mountains of China.
TOUR G: The Living Fossil: Finding Metasequoia
Lisa Pearson, Head of the Library and Archives
Metasequoia glyptostroboides, the dawn redwood, once thought to be extinct, was discovered growing in Hubei Province, China in the 1940s. Lisa Pearson discribed the exciting story of its discovery, showed archival objects from our collection, and toured the Arboretum’s dawn redwoods in the North Meadow.
TOUR H: Tilia Tales
Kyle Port, Manager of Plant Records
Lindens (Tilia spp.) are important street and landscape trees, particularly the littleleaf linden (T. cordata). Did you know the Arboretum holds over one hundred and thirty linden trees belonging to twenty different species? Kyle Port explored our seven-acre collection and discussed their nativities, use in the landscape, ecology, and ornamental qualities.
TOUR I: The Leventritt Garden
Rachel Brinkman, Assistant Manager of Horticulture
The Leventritt Garden is a unique place where smaller sun-loving shrubs and vines can grow and prosper without getting lost under the larger trees and shrubs of the Arboretum. In this garden, you can see our wild-collected species side-by-side with ornamental cultivars available in the trade. Rachel Brinkman shared the history of the Leventritt Garden and explored some of the interesting plant species, including a number of Arnold Arboretum introductions, found in the themed areas of the garden.
