A vibrant groundcover for the shade garden, Lamium maculatum ‘Anne Greenaway’ forms a 6- to 8-inch-tall mass of scallop-edged variegated leaves that glitter with chartreuse, silver and mint green. Clusters of small lilac-mauve flowers add to the display in late spring, but the foliage can last all year in mild-winter regions. Perennial.

This new Japanese water iris has a poetic grace, with large flowers of lavender falls veined in violet and a dark-purple central clutch of “petaloids.” Adds a lovely accent to summer water gardens when grown in a partly submerged container. Hardy in Zones 4-9.  heronswood.com

With commentary by Oehme, van Sweden principal Eric Groft. 

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 commentary by Oehme, van Sweden principal Eric Groft.

Producing thick clumps of stems from underground stolons, Pycnanthemum muticum “creates a massed volume in the garden, and its silver-gray foliage and almost-white flowers contrast with the grasses.” A tough plant, it takes to wet or dry conditions, sun to part shade.
