Agrimonia eupatoria

The fruits are achenes approximately 0.6 cm (0.2 inch) in diameter and each have a number of hooks that enable it to cling to animal fur and clothing.

[4] Agrimonia eupatoria is native to Europe and Southwestern Asia, where it grows in damp meadows, pasture, along stream banks, and among shrubs.

Common folklore held that it could cure musket wounds by being brewed into "arquebusade water," and ward off witchcraft.

[5][6] Traditional British folklore states that if a sprig of the plant was placed under a person's head, sleep would persist until it was removed.

[7][better source needed] The flowers with their abundant pollen supply attract hoverflies, flies and honey bees.

[9] It is a wild host for a few insect pest species (Stigmella fragariella and Coroebus elatus) that feed on loganberries, raspberries, and strawberries in Europe.
