Polygonatum is a genus of 50 species of hardy herbaceous plants from the north temperate zone. It is popular to grow them with ferns and under the shadow of trees or shrubs.
They can grow in any fertile soil but ideally they should be located in a woodland setting. Pot cultivation should begin in November when the roots are fug out and potted fairly close together 6-8 inch pots. Place them in a frame and cover with peat or similar material until growth appears above the soil. Keep them in a greenhouse and water generously but place them outside after flowering.
Polygonatum × hybridum, Solomon’s seal, below, is perhaps the best known ornamental variety. It has arching stems, bearing ovate leaves and small clusters of nodding, tubular creamy-white flowers tipped with green, followed by black berries.
