Foliage Scientist to Speak at Arnold Arboretum

Autumn Colors: A Mystery Revealed

David Lee, Tropical Botanist, Florida International University, will on Tuesday, Oct. 25, 7 to 8:30 p.m. at the Arnold Arboretum, Weld Hill Research Building, 1300 Centre Street, Roslindale.

Part of the magic of living in New England is the stunning display of autumn foliage. But how, exactly, does the shift from greens to crimsons, yellows, burgundies, and oranges take place? And why are we treated to such a display? Lee will explain some of the chemical processes, cellular communications, and fluid dynamics that take place within a deciduous plant come fall and also the signals to humans and animals that are communicated through plant pigments.
