Friday Fabulous Flower - Meadow rue


Well, it's almost Friday, so may as well do something in bloom.  The Meadow Rue right next to our patio is an elegant tall plant (5') with a spray of purplish flowers at the top.  This is a dioecious species, probably Thalictrum delavayi.  The flowers are basically either a cluster of stamens or a cluster of pistils with a whorl of several petalloid bracts below.  In another taxonomic affront to TPP's memory, Hepatica. has been placed in the genus Tahlictrum.  Some molecular study obviously nested it within the meadow rue genus and so for neatness the genus got changed.  The meadow rue generally flowers now in mid to late July, whereas Hepatica flowers in the very early spring.  It also has petalloid bracts, and unlike many spring ephemerals, its leaves do not die back but over winter above ground after turning a purplish brown, thus the liver leaf, that and it's three lobed. Oh,crap there is a weedy vine climbing the meadow rue.
