The Morris Arboretum of the University of Pennsylvania is a historic public garden and educational institution that promotes an understanding of the relationship between plants, people and places through programs that integrate science, art and the humanities. More than 13,000 labeled plants of approximately 2,600 types are growing in the Arboretum's living collection. The garden began in 1887 as Compton, the summer home of brother and sister, John and Lydia Morris, heirs to the I.P. Morris Company iron-manufacturing firm.
