Height 40-60cm. Upright stems with bluish-green lanceolate to elliptic leaves and loose heads of pale blue flowers from pinkish buds, 5-10mm long. The corolla limb spreading slightly and equal to, or shorter than, the tube. Rocky mountains in light woodland. This plant is generally too large for the rock garden and needs a site in semi-shade in humus-rich soil.
