P. officinale, is a species of flowering plant in the family Asparagaceae, native to Europe, the Caucasus, Siberia, the Russian Far East, China, Mongolia, Korea and Japan.

    Brief Summary
    provided by Ecomare
    The long stems of angular Solomon's seal hang in an arch, with the flowers all dangling on one side. This plant grows well on slopes. The stems tend to lie in the direction of the sloop, giving it an enchanting appearance in late spring when the flowers blossom. If you get very close to the blossoms, you can smell their sweet scent.The only insects able to drink the nectar from the long narrow flowers are those with long tongues, such as bumblebees. Later in the season, the flowers turn into blue-black berries. Watch out! As tasty as they may look, both the plant and the berries are poisonous.
