Dropwort

Filipendula vulgaris, commonly known as dropwort or fern-leaf dropwort, is a perennial herbaceous plant in the family Rosaceae, closely related to meadowsweet (Filipendula ulmaria). It is found in Europe, western Siberia, Asia Minor, the Caucusus and North Africa. It prefers dry pastures, mostly on lime rich soils.

The leaves and roots are a source of methyl salicylate (oil of wintergreen).
