Leaves bend upward on either side of the prominent midvein, like a boat keel. A velvety band of hairs extends downward from the junction of leaves on each side of stem. Edges of ponds and moist soils, wet meadows, shallow waters. Banks and flood plains of lakes, ponds, and marshes. Ditch edges, dikes, swamps, wet prairies, and poorly drained spots.
Pods dry beautifully and are often used in arrangements.
Flowers used fresh in arrangements, but ends must be seared to prevent wilting. Herbaceous perennial forming stately clump of upright stems with long narrow leaves and heads of fragrant soft mauve pink flowers, composed of many small intricate flowers. Will thrive in average garden soil, so long as it doesn't dry out completely, especially in spring. Actually quite drought tolerant despite penchant for water. May be removed with a hard stream of water or sprayed with insecticidal soap, or simply left alone.
