At Glenstone, a contemporary art museum in Potomac, Maryland, 90 acres of planted meadows, shrub thickets, and woodland glades stretch from the property borders to the museum buildings. Organically planted and maintained, this landscape illustrates how landscape architects, native plant consultants, and an in-house management team can collaborate in the service of ecology, art, and a stimulating visitor experience. Our day will combine classroom instruction with a heavy dose of field observation to illustrate how this ASLA award-winning landscape went from landscape plans to vibrant reality.
