danewort

Sambucus ebulus, dwarf elder, walwort, or danewort—among the rubbish and ruined foundations of the Priory.

Augier wrote one volume of verse, which he modestly called 'Pariétaire,' the name of a common little vine, the English danewort.

Parkinson, however, thinks the plant obtained the name of Danewort because it would cause a flux called the Danes.
