Achillea ptarmica (sneezewort, sneezeweed, bastard pellitory, European pellitory, fair-maid-of-France, goose tongue, sneezewort yarrow, wild pellitory, white tansy) is a species of herbaceous perennial flowering plant in the genus Achillea. It has loose clusters of white, button-like flowers that bloom from June to August. Its dark green leaves have finely toothed margins.
The name ptarmica comes from the Greek word ptairo (=sneeze) and means 'causes sneezing'.
The plant is poisonous to cattle, sheep, and horses. Symptoms are generally slow to develop, and include fever, rapid pulse, difficulty breathing, weight loss, drooling, spasms and loss of muscular control, and convulsions.
This is a hardy, drought-tolerant plant that prefers full sun and moist but well-drained soil. Propagation is by sowing seed or division in Spring. Numerous cultivars have been selected for garden use, including 'The Pearl' (a clonal variety) and 'Aunt Stientje'. Both have gained the Royal Horticultural Society's Award of Garden Merit.
