THALICTRUM

Genus of about 130 species of rhizomatous or tuberous perennials found by streams, in meadows and in moist, shady, often mountainous areas worldwide (except Australasia) mainly in northern temperate regions.

Not related to true rue (Rutaceae) the name results from the similarity of the leaves. Rather an undervalued plant whose frothy flowers float on the breeze.

UK natives are T. flavum, common meadow rue, a plant of meadows and fens and common in southeastern England, alpine meadow rue, T. alpinum, much smaller and most common in northwestern Scotland and lesser meadow rue from northern coasts and Wales.
