Polygonatum × hybridum, the garden Solomon's-seal, is a hybrid flowering plant, which is a cross between common Solomon's-seal (Polygonatum multiflorum) and angular Solomon's-seal (Polygonatum odoratum).
The plant tends to be more vigorous than either of its parent species.[1]
Like other members of the genus, Polygonatum × hybridum grows from rhizomes. The stems reach a height of about 1 m (3 ft), and carry pointed leaves arranged alternately. They arch over at the top so that the flowers, produced in Spring in small clusters at the junction between a leaf and the stem, hang downwards. Individual flowers are white with green tips and are slightly scented.[2]
Polygonatum × hybridum is suitable for sunny or partially shaded positions and is described as easy to grow.[2] It is fully hardy, down to at least −20 °C (−4 °F). It has gained the Royal Horticultural Society's Award of Garden Merit.[3][4] In gardens it is susceptible to attack by the larvae of Solomon's seal sawfly (Phymatocera aterrima), which feed on the underside of the leaves, rapidly reducing them to a skeletonised appearance.
Numerous cultivars are known:[2]
