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

  • Position: full sun
  • Soil: fertile, moist, well-drained soil (or John Innes no. 3 compost for containers)
  • Rate of growth: average
  • Flowering period: July to August
  • Hardiness: frost hardy (may need protection in winter)

    Large, rounded umbels of star-like, violet-blue flowers, which have a darker purple stripe down the centre of each recurved tepal, appear prolifically in summer. 'Northern Star' is one of the hardier agapanthus, while the deciduous foliage has a dark violet-blue flush at its base.

  • Garden care: Apply a balanced liquid fertiliser throughout the growing season. Towards the end of September ease back on the watering and feeding of plants in containers to allow the foliage to toughen up. Keep reasonably dry during the winter and protect the crowns with a dry mulch in the autumn. Divide plants that have become too big in spring.
