Andrea Wulf's The Brother Gardeners:
Botany, Empire, and the Birth of an Obsession
In the 18th century a number of wealthy men raced to collect plants new to England. Andrea Wulf has chosen to focus on one Peter Collinson and his Pennsylvania collector John Bartram and on Joseph Banks and his botanist Daniel Solander who was a protege of Carl Linnaeus in Sweden. These men and their many colleagues created a nation of gardeners and a style of landscaping that remains with us today. Wulf does their stories justice. A great book.
