Shade Plants | False Rue Anemone. A delicate looking but tough woodland plant that forms large colonies that flower in spring from March-May. Simple five-petalled white flowers rise above basal leaves that resemble columbine leaves. Leaves persist well through the season if sufficient moisture is present. Grow in moist humus-rich soil, light to full shade areas as a colonizing ground cover.
PNW Best Perennial: Solomon's Seal (Polygonatum odoratum) looks delicate with its graceful, arching form and dangling summertime bell-shape flowers, but it's actually a tough-as-nails wildflower for the shade. Slowly forms large colonies, perfect for replacing shaded areas of the lawn where grass struggles to survive. Shade and moist, well-drained soil Size: To 3 feet tall and 1 foot wide
