Care of the plant Polygonatum odoratum or Solomon's-Seal.

Care of the rhizomatous plant Polygonatum odoratum or Solomon's-Seal

The genus Polygonatum, family Asparagaceae, comprises 60 species of rhizomatous plants native to Eurasia. Some species are: Polygonatum odoratum, Polygonatum verticillatum, Polygonatum biflorum, Polygonatum multiflorum, Polygonatum humile.

Common names: Solomon's-Seal, Angular Solomon's seal, Scented Solomon's seal. This species is native to Europe and Asia.

They are perennial herbaceous plants with a cylindrical rhizome and arched branches that reach 1.5 meters (4.92 feet) in height. The leaves are elliptical in shape and a beautiful bright green color. They produce attractive white hanging tubular flowers with a green tip. They bloom in late spring. The round blue fruits are also attractive.

They are used in undergrowth under trees or large shrubs, on steep north-facing slopes and on shady edges.

Polygonatum odoratum prefers a shady exposure but also grows in semi-shade; direct sun does not suit them in Mediterranean, tropical or subtropical climates. They do not resist heat well, but they do resist intense frosts.

The soil must be acidic, well drained, and contain abundant organic matter. Planting is done in spring or autumn.

Water regularly, waiting for the surface part of the substrate to dry.

Fertilize with compost or manure in late winter and with mineral fertilizer every 15 days during spring and until flowering ends.

They can be intensively pruned at the end of winter to favor the next flowering.

They are plants prone to attack by aphids, caterpillars and snails.

They are easily propagated by division after flowering.
