Blooming now in the shaded patch of tranquility known as the Cherbonnier English Woodland Garden is this evergreen azalea, Rhododendron 'Roblef' Encore Autumn Sundance. Also in bloom: Yellow wax bells, Kirengeshoma palmata. The garden exemplifies an English style noted for its informal display of botanical treasures from around the world. It's arranged in ‘garden rooms,’ with clusters of the same or similar plants to draw people from one room to the next. A key attraction of the English Woodland Garden is the meandering brook that flows from a pool in the northeast corner, under several limestone bridges, and into the Japanese Garden lake by way of a waterfall.
