Extremely showy and exotic-looking, Crocosmia produce decorative clumps of erect sword-shaped leaves and brilliant wands of fiery scarlet, red, orange, and yellow tubular flowers which bloom for 5-8 weeks from mid summer through mid fall. Magnets for hummingbirds and butterflies, the vibrant blossoms give way to seedpods that persist into fall and attract hungry birds.

  • Crocosmia is a genus in the Iridaceae family from tropical and eastern South Africa, which includes 8 species of crocosmia plants as well as many hybrids. 
  • Crocosmia are great perennials for the late season garden as they provide weeks of vibrant colors when many other perennials are starting to fade.
  • Resembling the foliage of sword-lilies, Crocosmia's narrow, bladed leaves also provide interesting vertical accents in the borders. 
  • Crocosmia grow up to 1-5 ft. tall (30-150 cm) and begin to produce their lovely blossoms in the summer.  
  • Crocosmia make excellent border plants, providing color and contrast to the perennial border. They look spectacular in front of green conifers, among dark leaved dahlias and cannas or next to blue-flowering plants such as Agapanthus (Lily of the Nile), Aconitum (Monkshood) or Echinops (Globe Thistle). They should be planted in clumps of 12 or more.
  • Crocosmia may be grown in containers - make sure you select a large pot with drainage holes.
  • Crocosmia are wonderful cut flowers and will last up to 2 weeks in a vase. 
  • Crocosmia are easily grown in moderately fertile, humus-rich soil that is moist but well-drained. They thrive in full sun or partial shade where they will multiply rapidly and readily. 
  • Tolerant of summer heat and humidity, Crocosmia are also drought tolerant (once established), salt tolerantdeer and rabbit resistant
  • Plant crocosmia bulbs (more exactly "corms") in spring. It is recommended to dig up the corms in late fall in hardiness zones 5 & 6 and store them over the winter until the next spring. In other cold areas, add a generous amount of mulch, to protect your plants from freezing.
  • Propagate by division or by corm offsets.
  • Crocosmias should only be divided every 3-4 years in late fall.
