Solomon’s Seal (Polygonatum odoratum ‘Variegatum’) is the Perennial Plant Association’s 2013 Perennial Plant of the Year™. This all-season perennial has greenish-white flowers in late spring and variegated foliage throughout the growing season. The foliage turns yellow in the fall and grows well in moist, well-drained soil in partial to full shade.
Often called variegated Solomon’s Seal, striped Solomon’s Seal, fragrant Solomon’s Seal and variegated fragrant Solomon’s Seal, this plant is one great performer in the garden. Regardless of its location, members of Polygonatum are excellent perennials for the landscape.
The genus botanical name (Polygonatum) comes from poly (many) and gonu (knee joints) and refers to the many-jointed rhizome from which the leaves arise. The common name Solomon’s Seal has several proposed derivations. The first is that the scar that remains on the rootstock after the leaf stalks die off in the fall resembles the seal impressed on wax on documents in the past. The second source is that John Gerard, the English botanist and herbalist, suggested that the powdered roots were an excellent remedy for broken bones. He also felt that the plant had the capacity for “sealing wounds,” which was why the perennial received the common name – Solomon’s Seal.
Solomon’s Seal grows 18 to 24 inches tall and will spread by rhizomes to form colonies. The oval-shaped leaves are carried on upright, arching, unbranched stems. The variegated leaves are light green with white tips and margins. Leaves turn an attractive yellow in the autumn. Sweetly fragrant, small, bell-shaped white flowers with green tips, are borne on short pedicels from the leaf axils underneath the arching stems. Bluish-black berries are sometimes present in the autumn
Variegated Solomon’s Seal is a classic beauty for the shady woodland garden or the part-shade to full-shade border. It is a great companion plant to other shade lovers including hostas, ferns, and astilbes. The sweet fragrance will enhance that walk along a pathway on a spring morning. Flower arrangers will find the variegated foliage to be an attribute for spring floral arrangements. And finally, this all-season perennial offers yellow fall foliage color.
