Description
Introduction to Solomon’s Seal (Polygonatum x hybridum)
Solomon’s Seal (Polygonatum x hybridum) is a hardy, long-lived, rhizomatous perennial herb belonging to the Liliaceae family, native to Europe and Asia. In spring, its rhizomes produce long, arching stems adorned with mid-green, oval-shaped foliage. By summer, the plant displays charming white, bell-shaped flowers with green tips, gracefully hanging beneath the leaves in clusters of 2 to 7. Once the flowers fade, they are replaced by small, dark purple berries that hang below the leaves. Be aware that these berries are poisonous and should not be consumed.
Solomon’s Seal is ideal for growing under trees and can thrive in woodland settings or shaded borders. It complements shade-loving plants like ferns and hostas, adding height and texture. Its elegant stems and flowers also make stunning, long-lasting additions to floral arrangements.
Receiving and Storing Bare-Rooted Solomon’s Seal
Upon receiving your bare-rooted Solomon’s Seal, inspect the rhizomes for any signs of damage or disease, ensuring they are firm and free from mould or rot. Soak the rhizomes in lukewarm water for about 30 minutes to an hour to rehydrate them. Prepare a shaded or partially shaded spot (refer to climate information) with well-draining soil, incorporating well-broken-down animal manure, blood and bone, or a complete fertiliser into the soil. Dig a hole large enough to accommodate the rhizomes without bending them, ensuring the buds are buried 3-5 cm deep and 25 cm apart. Place the rhizomes in the hole, backfill gently with soil, and water thoroughly to settle the soil and eliminate air pockets. Apply a layer of organic mulch around the plants to retain moisture, regulate soil temperature, and suppress weeds.
If not planting immediately, gently brush off excess soil from the rhizomes and allow them to air dry for a few hours. Store the rhizomes in a breathable container with a dry, inert material like peat moss, vermiculite, or dry sand, and keep them in a cool, dark, and dry place with temperatures between 1.5-10°C (35-50°F), ensuring the area is frost-free and has good air circulation. Periodically check for signs of mould, rot, or dehydration, removing any affected rhizomes. When ready to plant, acclimate the rhizomes to room temperature a few days prior and soak them in lukewarm water for about 30 minutes to rehydrate them before planting. This careful handling will ensure your Solomon’s Seal remains healthy and ready for planting.
