Common agrimony (Agrimonia eupatoria) from an underground rhizome sends up an erect stem, which in its upper part is clothed with short and long hairs and sparse glandular hairs. The leaves are pinnate. Basal leaves form a rosette, stem leaves are arranged spirally. The stem leaves are at mid-height of the stem long between 10 and 30 cm and mostly divided into 5 to 9 larger coarsely serrated leaflets, among which there are also small leaflets. The lower surface of the leaflets is woolly-haired and therefore greenish gray. The teeth of the leaflets are more or less blunt. Numerous yellow flowers form a long, dense raceme. The yellow petals are rounded at the top. Green sepals are arranged in one whorl. The ripe fruits are ribbed for at least 3/4 of their length. The outer hooked spines on the upper part of the fruit are upright to horizontally protruding. With the spines the fruits of agrimony cling to the fur of animals, which disperses the fruits with the seeds around.

Common agrimony grows on moderately fertile, fresh soils on a base-rich substrate. It can be found in sunny places throughout Slovenia from the lowlands to the mid-mountains.
