Nature is always in bloom at Swarthmore College's Scott Arboretum. Formed in 1929, this "living memorial" to Arthur Hoyt Scott, a member of Swarthmore College's graduating class of 1895, supports over 4,000 kinds of ornamental plants, trees, shrubs, perennials, and vines on 300 acres.
Here, your best strategy is to pick up a map to the arboretum, and be sure to visit areas at their peak. For instance, blooming plants and cherry trees in the spring, and in the fall, trees set ablaze with autumn colors. Make a point to also stop by the the Arboretum offices, which house an extensive library of botanical and garden literature. Open every day from dawn to dusk, the Scott Arboretum does not charge admission.
