How to Grow

Cultivation

Grow in humus-rich, well drained soil in an open, sunny spot; these plants like moisture during the growing season but dislike winter wet. Add a compost mulch in spring. May benefit from winter protection in colder areas. See dierama cultivation for more detailed advice

Propagation

Propagate by division of mature clumps, carefully separating corms in spring. Young plants and divisions can be slow to establish

  • Coastal
  • Cottage and informal garden
  • Prairie planting
  • Gravel garden
  • Flower borders and beds

Pruning

Tidy any winter-damaged foliage by cutting to the base in spring
