Tall and slender, Thalictrum delavayi (Chinese Meadow Rue) is an upright herbaceous perennial, favored for its lacy, refined, green foliage and its airy clusters of pendulous, lilac-mauve flowers adorned with conspicuous creamy stamens. Borne on wiry, purple-tinted stems, they bloom profusely from mid-summer to fall. This Chinese Meadow Rue adds elegant vertical lines to the garden. Being a 'see-through' plant, it is quite versatile and may be placed in front of drifts of shorter perennials or at the back of borders where it will act as a delightful foil.
