Thalictrum dioicum, the early meadow-rue[1] or quicksilver-weed, is a species of herbaceous plants in the family Ranunculaceae.

Thalictrum dioicum grows from 30 to 80 cm tall, from upright caudex, with yellow-gold colored – thick fibrous roots.

The filaments end in anthers 2–4 mm long that are mucronate to acuminate in shape with purple colored stigma.

After blooming, female plants if fertilized, produce green fruits called achenes.

[2] Plants are grown in shade gardens for their attractive lacy foliage that is reminiscent of columbines or maiden hair fern.
