Oh good! I hope it does well!

What is the difference between Thalictrum rochebrunianum and T delavayi? I've never been able to figure out which one I have. When I google, the flowers look the same. Mine get quite tall in CT, about 6', but in Southampton, where I grew the parent plants in more sun, they were shorter. This year I moved a bunch of 2 yr old seedlings to a brighter spot, hoping they'll show up better. Pic is a mature plant, from 2011.
