Thalictrum is a genus that’s comprised of 120-200 different species with 22 of the species being found in North America. The common name for the plant is “meadow rue” and its natural habitat is in damp and shady locations. We have a grouping of Thalictrums that showed up on their own and grow naturally along our drive in a very damp spot that gets plenty of run-off after rainstorms. They are likely Thalictrum polygamum, being very tall and having white star-shaped flowers and the characteristic columbine-like foliage. And then there are the Thalictrums that we plant in the garden for their beautiful and delicate flowers, like this Thalictrum rochebrunianum 'Lavender Mist’ that can look great arching over the back of a border.
