'Rhapsody in Blue' PP15148 was selected by renowned plantsman Piet Oudolf of The Netherlands for its superior flowers and upright, bushy habit. A profusion of brilliant blue-violet flowers appear on branched flower spikes above the grey-green foliage beginning in early summer. If cut back, it often reblooms.
This is a clump forming perennial with oblong leaves which are aromatic when crushed. The flowers add great texture and fragrance to both fresh and dried bouquets. Use this plant in containers or the middle of the flower border.
