  With spikes of intense blood-red flowers that open over a long period from even darker buds, 'Blackfield' is a first rate perennial that not only looks great, but it will also help attract beneficial insects including bees. Even when not in bloom, the relatively large (to 10cm in length) oval to heart shaped foliage offers interest.
  
  
• Garden care: Incorporate a generous amount of composted organic matter or well-rotted manure into the backfill during planting. Once established, lift and divide congested columps in spring or autumn. Cut back after it has finished flowering, or wait until late winter or early spring. Apply a mulch of composted organic matter every year.
