A long bloomer, from midsummer through September, 2- to 3-foot Agastache ‘Black Adder’ “has the always-pleasant lavender-purple color that goes so well ‘out East.’” A magnet for butterflies and other nectar-seeking insects, the foliage and flowers also release a minty fragrance when brushed against.
With its ample sprays of small, fragrant white blossoms and lustrous dark-green foliage, Clematis terniflora (also called virgin’s bower) is “a beautiful cascading vine that grows fast and blooms in August when all the Hamptonites are in their gardens.” If it gets out of bounds, it can take a hard pruning and will easily rebound.
