Blue-Eyed Grass Growing and Maintenance Tips
S. montanum can tolerate moderate drought. Sisyrinchium is best grown in a moist but not wet soil, in full sun to partial shade. They will self-seed in optimum conditions, so it is best to remove the flowers before they seed. Plants should be divided every few years to maintain health.
