“Solomon’s seal is one of those spring plants that make your heart beat faster,” Aldona Satterthwaite says about the perennial plant whose arching leaf and white drooping flowers signal spring. A master gardener, Aldona is executive director of the Toronto Botanical Garden and knows of what she speaks.
Fellow master gardener Belinda Gallagher of Hooked on Horticulture, agrees. “Solomon’s seal is my favourite plant of all times–today,” she says. “It takes dry shade, and is very elegant and graceful. I love the flowers, but particularly the arching shape of the stems. They emerge like sea serpents from the ground in the spring.” The native Solomon’s seal grows 60 to 70 cm both in height and width and grows well in a dry, shady spot from zones 3 to 9.
Solomon’s seal adds grace to the garden. It can be featured as an accent or woodland plant, or used as a cut flower.
Delicate, white bell-like flowers hang from gracefully arching stems in late spring. The small flowers are self-cleaning and will drop off naturally. The foliage remains attractive all season, so the plant is virtually maintenance free. The stems even disconnect from the rhizomes on their own after a frost. But before that, the foliage turns a golden yellow.
Belinda explains that Solomon’s seal is usually misnamed in garden centres. The native and non-native (mainly from Asia) are often mixed together. “I like them all,” she says. “The variegated ones are wonderful, but take a longer time to mature and bulk up so people may be disappointed.”
To me that is a good thing, since that means they are less invasive in the garden. The variegated Solomon’s seal is my favourite, since its arching stems of green leaves are edged in white, brightening the shade. They are scented, which is an additional gift.
Note: The other recommended varieties of polygonatum in Gardening from a Hammock may not grow as quickly as the native species, but are valuable additions to any shade garden. Check out Giant Solomon’s seal (Polygonatum commutatum), which makes a statement in any garden as it grows from 90 to 120 cm high.
