This summer-blooming umbellifer (family Apiaceae) is related to the garden plant, Angelica archangelica, that is used for culinary purposes.

Wild angelica grows in damp places, and in particular beside lakes and streams; this wildflower can reach a height of two metres but more commonly grows to about a metre tall.

This is a perennial plant, and its purplish stems are almost hairless, which helps distinguish it from the rather earlier-flowering hogweed. In Wales and throughout most of the UK, wild angelica can be seen in bloom from July through until September.
