I bought a plant of yellow meadow rue (Thalictrum flavum glaucum) about ten years ago for no particular reason that I remember now. I planted it in my parents garden. Now it looks like this. I love it! It is the blue-green mass in the middle with the sulfur flowers. It is usually more upright and orderly but it has rained a lot this year.

and the foliage.
