| Lady's Mantle Alchemilla mollis ‘Auslese’ |
It is a tough perennial bearing clusters of sulphur-yellow flowers throughout summer. New foliage appears and unfolds from an accordion or fan to reveal a lotus-skinned mature leaf. Tiny hairs on its surface caused water droplets to suspend in dots from evening morning dew. It is a very unique but underutilized ground cover. This easy herb can be mowed to 3” high.

| Leadwort Ceratostigma plumbaginoides |
Plumbago (also commonly called leadwort) is a wiry, mat-forming perennial which spreads by rhizomes to form an attractive ground cover. Typically grows 6-10" tall on generally erect stems rising from the rhizomes. Oval to obovate, shiny, medium green leaves (to 2" long) turn bronze-red in autumn. Terminal clusters of 5-petaled, gentian blue flowers (1/2 to 3/4" diameter) appear above the foliage over a long summer to frost bloom period. Flowers resemble those of woodland phlox. It is an amazing yet underutilized ground cover.

This rare and highly-prized, tropical-looking, oriental native provides the appearance of an evergreen hosta.

Late in the season, the insignificant flowers produce short stalks of red berries that persist through the winter at the base of the plant. When used en masse, Rohdeas are a dynamite evergreen addition to the deep shade garden for a presence even in winter.
