Squinancywort

Asperula cynanchica (squinancywort or squincywort) is a species of flowering plant in the Rubiaceae family. Its common name is derived from its former use as a medicinal herb to cure quinsy. It is native to much of southern and central Europe from Spain and Ireland to Russia.

In Sweden, the roots have been used as a red dying agent.

It is a perennial plant and grows in short grassland or sand dunes on calcareous soils. The flowers are small and can be either pink or white.
