Description

This plant from the Rocky Mountains bears many bright blue flowers on long slender spikes above a low growing basal mound of  leaves.

It likes a well drained  fertile soil in full sun and  requires minimal care.

Deadhead the plant to prolong the flowering season. Cut the plant back to base in the winter. Propagate via softwood cuttings in early summer or semi-ripe stem tip cuttings in summer-autumn. Divide established clumps in spring.

Sowing advice

Sow in Autumn in a cold frame or directly in early winter. Surface sow onto moist, well-drained seed compost. Just cover seed with fine gravel or similar. Place in a cold frame. 8 weeks at 4°C is needed. Natural winter cold should offer ideal conditions for germination to occur as the weather warms in spring. Germination can be slow and erratic and may require another winter cold period to occur. Seed must be kept moist. Transplant seedlings when large enough to handle or plant out.
