An official Path Through History Site! Listed on the National Register of Historic Districts, Planting Fields Arboretum State Historic Park was the home of William Robertson Coe from 1913 to 1955. The intact former Gold Coast estate, offers two acres of greenhouse displays, 22 different gardens, historic landscape, woodland paths, more than 10,000 different types of plants and beautiful architecture including Coe Hall, a 65-room Tudor Revival mansion. Coe, who held an interest in rare plants, developed the 409-acre estate into an arboretum with 160 acres of garden and plants. Many trees and shrubs hail from Europe and Asia, and there are more than 600 types of rhododendrons and azaleas, which peak in May. From mid-August to mid-October, the outdoor dahlia strolling garden is awash in all the colors of the rainbow among hundreds of blooms of all shapes and sizes.
