How to Grow and Care

Plants are usually started by transplants or rhizomes. Seeds of Polygonatum can take up to 2 years to sprout so that you will get some seeding in established plantings.

Solomon's Seal like a rich organic soil with a pH in the acidic to the neutral zone. They need some shade to thrive truly. The damp shade is even better, although once established, they are quite drought-tolerant. Plants can be started in the spring or fall. Plant only 1 to 2 inches (2.5 to 5 cm) deep and about 2 to 3 inches (5 to 7.5 cm) apart.

Solomon's Seal seldom needs division. It takes several years before a clump is large enough to divide for propagation purposes. When ready, divide in early spring or fall and leave several buds on each division for the best success. The rhizomes can be divided even further, but it will take longer for them to become established. Another option is to remove and plant just the offsets at the edges of a clump.
