Solomon's seal

RHS Genus Guide

Solomon’s seal (Polygonatum) is a genus of long-lived, herbaceous perennials, most with graceful, arching stems and simple hanging flowers. They are ideal for damp, shaded or woodland gardens, providing early-season interest and a touch of elegance.

Botanical name: Polygonatum

Common name: Solomon's seal

Appearance

Solomon’s seals typically grow between 50cm and 1m. They have neat pairs or whorls of leaves along the stem and, in late spring to early summer, dangling, tubular flowers. These are often creamy-white and green but can also be dusky pink or mauve and may be followed by red or black berries.

Preferences

They generally like moist but well-drained, fertile soil in partial to full shade. A sheltered location helps prevent damage to the tall stems.

Dislikes

Dry or waterlogged soils are disliked, and most do not enjoy full sun, although the exceptionally tall, smooth Solomon’s seal (Polygonatum biflorum) does.

Did you know?

Solomon’s seal has been traditionally used in herbal medicine across Asia for its purported anti-ageing, anti-fatigue and anti-diabetic effects. The name comes from the seal-like markings on the rhizomes.
