These perennials, native to many areas of North America, are admired for the blue berries that dangle from arching, unbranched stems in the late summer or early fall. The bell-shaped flowers are pale greenish-white and 1/2 to 1 inch long. They are borne in clusters beneath the leaf joints and bloom in the late spring. Small Solomon's seal grows 1 to 3 feet tall and usually bears clusters of one to three flowers, while great Solomon's seal reaches 2 to 6 feet in height and produces up to 10 flowers in each cluster. A lovely plant in any season, the foliage will tint yellow in autumn. Plants are deer resistant.
This plant is well suited to Northeastern Coniferous, Southeastern Coniferous and Deciduous Woodland and the Prairie environments. Provide partial to deep shade and humus-rich soil with a pH of 4.5 to 5.5 for small Solomon's seal and a pH of 5.0 to 7.0 for great Solomon's seal. The larger species, which frequently grows along streams, requires very moist soil, while the smaller does well under drier conditions. Plant rhizomes in spring or fall. They should be 1 to 2 inches deep and 12 inches apart with the tips of the growing shoots just below the surface of the soil. Plants can also be raised from seeds sown in the fall, but they take two to four years to flower. Plants can be divided in the spring. Established plants spread by rhizomes, and also reseed themselves.
A small, 15-inch high perennial, corydalis (Corydalis lutea) has bluish-green leaves that resemble those of culinary Italian parsley. Its tiny, yellow flowers resemble the flowers of bleeding heart. Corydalis prefers to be planted near rocks in slightly alkaline soil that is well-drained and gravelly. It is an ideal plant for a rock garden or a stone wall. Although it does best in partial shade, corydalis will also grow in full sun. It is a prolific reseeder, although it is difficult to start from seed, due to its complicated stratification requirements, according to the University of Vermont Extension.
False Solomon's Seal
Found in moist woodlands, false Solomon's seal (Smilacina racemosa) grows up to 3-foot long unbranching, arching stems with dark green, alternate leaves. White to yellow flowers appear on a spike which grows out from the terminal end of the stems. Solomon's seal prefers partial to full shade and blooms in late spring.
A fast-growing 3 to 4-inch high evergreen perennial, ajuga (Ajuga reptans) prefers shade to partial shade and sandy, well-drained soil, although it tolerates clay soils. Its glossy, dark, evergreen leaves emerge with a reddish tint before turning green. In spring it produces blue-violet flowers on short spikes. Ajuga works well in moist areas. Because it is so attractive to bumblebees, it is an excellent choice for a bee garden.
