This is a detailed view of one of the National Capitol Columns located at the National Capitol Columns Overlook, situated between the National Herb Garden and the Azalea Collections. This is one of the few flowers you will see at the Arboretum that is carved in stone [and therefore is believed to be hardy in
USDA hardiness zones 1 through 11]. It is thought that it is a representation of
the southern magnolia, Magnolia grandiflora.
