Seeing the Forest Through the Blue Trees

Konstantin Dimopoulos

Konstantin Dimopoulos is the artist behind the ongoing global environmental art installation, The Blue Trees. He created this iconic artwork in response to what he calls the insanity behind the wanton destruction of forests and oceans for greed, convenience, and short term gain. The Blue Trees is a visual scream, an attempt to give trees and their ecosystems visibility and voice.

Insects Visiting the Flowers of Woody Plants

Nate Erwin

Flowering plants and insects have an intertwining history, dating back 130 million years. Insects were there ready to take advantage of a new source of protein and sugar when plants evolved flowers to reproduce. Plants evolved new strategies not only to fend off insect herbivores, but to lure insects to their food-rich flowers in exchange for reproductive services. Different species of trees, shrubs, and vines lure different insects to help in the process of passing on genes to the next generation. This presentation explores the diversity of insects that aid woody plants in their reproductive efforts to produce seeds, nuts, and fruits.

Into the Wild: Tapping into the Genetic Potential of North American Native Plants

Tim Boland

Legendary American horticulturist Polly Hill devoted her life to raising plants from seed. Through trial and error Polly would eventually name dozens of plants and her private Arboretum would become a public garden in 1998. Inspired by her devotion to raising plants from seed, today the Polly Hill Arboretum travels far and wide in North America collecting plants that bring the potential of new discoveries to enliven our collections and gardens with beautiful plants. Join Tim on some of his past adventures and learn about future genetic potential within the temperate flora of North America.

Urban Nature: Human Nature

Peter del tredici

Urban ecosystems are the ultimate manifestation of the dynamic interaction between humans and nature, between our desire for neat, orderly landscapes on the one hand and our fear of messy ecological chaos on the other. This presentation will focus on the plants that grow spontaneously in cities, some native some non-native, and their remarkable ability to flourish in spite of stressful environmental conditions. This urban vegetation is as cosmopolitan as the human population and plays an important role in helping to clean up the mess we have made of the planet by lowering air temperatures, absorbing storm water runoff, and trapping particulate matter. Like it or not, this vegetation reflects our irrevocable past and portends our unpredictable future.
