I just sent some Crocosmia to a friend in KS and sent this off to him when he asked
about care.
Grow crocosmia in moist but well-drained soil in full sun to partial shade. Divide congested clumps every three to five years to rejuvenate them and encourage better flowering. In colder regions you may need to mulch the corms to protect them from frost. Perennial in zones 5-9. In colder climates, you may need to lift the crocosmia corms in the fall and store them indoors over winter.
