#310 Tall Hairy Agrimony (Agrimonia gryposepala)

09 January 2021

The plant grows 1–5 ft (about 30–150 cm) high, producing a cluster of small, yellow, 5-parted flowers on a hairy stalk above pinnate leaves. The fruits are hooked dry seeds grouped in a cluster. A spicy scent is released when the stem is crushed. The plant’s native range covers most of the United States and Canada (except the Rocky Mountains) and extending south to Chiapas, Mexico. It grows in woodlands and forests.

The specific epithet, gryposepala, is derived from the Greek grypos, meaning curved or hooked, and from sepala, meaning sepal. The name “grooveburr,” which is sometimes applied to the plant, comes from the grooved shape of the seedpod or burr.
