This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

• Position: partial shade
• Soil: moderately fertile, humus-rich, moist, well-drained soil
• Rate of growth: average
• Flowering period: April to July
• Hardiness: fully hardy
  
  Fern-like foliage, often with a bronze flush, forms a spreading mat that is topped with clusters of prominently-spurred, sky-blue flowers in late spring and early summer. A pretty plant for the woodland floor, or front of a partially shaded border.
  
  
• Garden care: Cut back stems to near ground level during November, earlier if self-seeding is a problem. Lift and divide congested colonies in the autumn.
