Growing up to 3m (10ft) or more in height when flowering, these beautiful plants produce tall spires with large scented blooms in early summer. The mid to dark green heart-shaped leaves form attractive hosta-like rosettes on immature plants.
Short-lived, cornflower-like perennial with clumps of linear, grass-like hairy leaves up to 12 inches long. In mid-summer to autumn, bears blue to lilac-blue flowerheads 2 inches across, with darker centers. Combines well with echinacea, grasses and hemerocallis.
The broadly strap-shaped grey green leaves emerge in spring and die back as the flowers umbels mature and the blooms open in summer. The attractive seed heads persist in the garden or may be cut for dried arrangements.
