Can you please identify this 9 foot perennial. I planted it in 2013 or 2014 and have lost the name and source.
Thank you for sending this photo. You have a meadow rue, possibly Thalictrum rochebruneanum, commonly known as ‘Lavender Mist’ meadow rue. You must have it in ideal soil and site conditions if it is 9 feet tall. Generally it grows to 6 feet.
Enjoy your beautiful perennial!
