Polygonatum multiflorum or Solomon's seal is a vigorous perennial that spreads by rhizomes producing long, arching stems that have broad, bright green leaves.
In summer it bears pendulous, tubular white flowers that have yellow tips and hang down from the branches elegantly.
Small black fruits follow the flowers and are also an attractive feature of the plant.
This plant can become a little too vigorous in perfect conditions, so it's important to keep an eye on its spread to prevent it from becoming invasive.
