Yellow meadow rue (Thalictrum flavum subsp. glaucum, also known as T. speciosissimum) is a beauty in the border, with clumps of ferny, gray-blue foliage that send up 3- to 4-foot-tall stems topped with fluffy, yellow blooms in early to midsummer. Full sun (especially if the soil is on the moist side) to partial shade. Perennial; Zones 4 to 8 or 9.
2021-collected seed sold out. I hope to collect again in August 2022. At least 20 seeds.
