Yellow Meadow Rue, Dusty Meadow Rue, Glaucous-Leaved Yellow Meadow Rue, Thalictrum flavum 'Glauca', Thalictrum speciosissimum


Thalictrum flavum subsp. glaucum (Yellow Meadow Rue) is a robust, rhizomatous, clump-forming perennial boasting striking silvery blue leaves divided into many leaflets. The foliage is so handsome that it is prized in floral decorations. In early to midsummer, clouds of slightly fragrant, fluffy yellow flowers appear above the foliage. Perfect, the flowers consist of pale yellow sepals and bright yellow stamens, and are held in an upright pyramidal panicle, 2-4 in. across (5-10 cm). Magnificent in bloom, Yellow Meadow Rue is equally beautiful when not in bloom, thanks to its glaucous foliage. Low maintenance, deer resistant, it is fairly tolerant of warm, humid summers. Thalictrum flavum subsp. glaucum is highly effective in the garden.
