Tree Mob™! Genetic Giant: Sequoiadendron giganteum

The giant sequoia (Sequoiadendron giganteum) is the largest tree species on earth. Yosemite National Park’s Mariposa Grove in California has approximately 500 mature sequoias today. The oldest specimens there are over 3,000 years old. The Arnold Arboretum currently has six giant sequoias in its collection. We will gather by the largest specimen which stands at roughly 60 feet in height and has a diameter of over 55 inches. The tree was originally collected by financier and yachtsman Chandler Hovey in 1948 and stood in a grove near the Boston College Campus at the Slade-Hovey House. After acquiring the property in 1970, BC President Seavey Joyce donated the then 42-foot tall tree to the Arboretum in honor of its Centennial in 1972. Manager of Horticulture Andrew Gapinski and Curator of Living Collections Michael Dosmann will speak about the challenges faced by this western species growing in New England and the effects of a changing climate on the longevity of this particular specimen. Meet at 6:00pm on Thursday, July 23 in the conifer collection at Acc. # 1320-72*A. If you can’t attend this mob, join us on August 9 for a celebration under this tree.
