The magnificent bloom of the extremely rare Franklin tree, now extinct in the wild. They are like late-summer magnolias with their vibrant and fragrant flowers. Once native to the Southeastern United States, the Arnold Arboretum now boasts the two largest specimens in North America. They are here thanks to the foresight of naturalist William Bartham and his son, who collected seeds in 1776 in Georgia, and then donated a tree from the family garden to Harvard in 1884. This fruit takes more than a year to develop. You can see the tight, round buds to the left.
