Thalictrum dioicum early meadowrue


Early meadowrue is a dioecious herb (male and female flowers appear on different plants) with delicate lacy leaves and distinctive fruit. This is the first meadow-rue to bloom and produce fruit. Blooming is done by end of May and achenes are visible by then. Early meadow-rue is similar in appearance to tall meadow-rue (T. pubescens). Tall meadow-rue is significantly taller and starts blooming about the time early meadow-rue goes to seed.
