The Lee and Virginia Graver Arboretum is a 63-acre botanical garden and arboretum in Bushkill Township near Bath, Pennsylvania, owned by Muhlenberg College and open daily without charge. It began as the private work of Dr. Lee Graver and Virginia Graver, who spent more than 40 years developing the property with wildflowers, ferns, rhododendrons, and native and rare trees before donating it to the college in 1994. Especially known for its conifers, with more than 150 species, it also features woody plants and habitat-based plantings, including wetland species, combining ornamental horticulture with a strong emphasis on native ecosystems.
