Description: 'Taw Valley' is a herbaceous perennial to about 80cm, producing a clump of narrow, glossy, strap-shaped leaves. Rounded umbels of deep blue, funnel-shaped flowers appear from mid-summer to mid-autumn.
Care: Grow in fertile, moist but well-drained soil in full sun or grow in a container. In cold areas, mulch well overwinter and take containers under cover. Propagate by division every three to four years in spring. In late autumn remove any remaining leaves, but seedheads can be left as they look attractive over winter.
