PA – Graver Arboretum

Located in Bushkill Township, Northampton County, 22 miles from the Muhlenberg College campus, the 66-acre Graver Arboretum was donated by Dr. Lee Graver (’31) and his wife Virginia in 1994. The Arboretum is used as an outdoor classroom by the biology and other science departments but is open to the public seven days a week during daylight hours. (No dogs please.)

In addition to extensive plantings of rhododendrons and azaleas, as well as native wildflowers, the Arboretum has a collection of more than 130 species of conifers from around the world. Although new specimens are added annually, many of the original plantings are about 50 years old, and are full-sized mature examples of their type.

With the help of a grant from the American Conifer Society, a recent addition has been a dwarf conifer garden, with more than 20 examples of species appropriate for backyard gardens. These include Metasequoia glyptostroboides Bonsai’, Microbiota decussata, Abies koreana Silberlocke’, Taxus baccata Amersfoort’, Pseudotsuga menziesii Cupressiana’, Chamaecyparis obtusa Gracilis compacta’ and Tempelhof’, Juniperus communis Gold Cone’, Picea glauca Pixie Dust’, Picea abies Pusch’, and Pinus parviflora Oliver’s Garden’.
