Tree adaptability (IMAGE)
Caption
Botanic gardens grow tree species from all around the world. This photo of the serene Japanese Garden at the Denver Botanic Gardens includes several species of pine, spruce and fir trees. Arboreta, such as botanic gardens, were used in research led by Daniel Laughlin, a professor in the UW Department of Botany, to understand the range of temperatures that trees can tolerate.
