A plant, possibly a form of dock or sorrel, named for its relationship to blowing or wind; historical botanical term.
From blaw (blow) plus -wort (a plant), a common Old English and Middle English suffix for naming plants. The specific plant identity is uncertain in historical records.
The -wort suffix named plants based on where they grew, who used them, or their appearance—mugwort, liverwort, milkwort—giving us a whole vocabulary layer from medieval herbalism.
