Growing and Maintenance Tips
Iris cristata needs organically rich, medium moisture, well-drained soil in part shade. It will tolerate close to full shade. The more sun it receives the more there is a need for regular watering. Plants will quickly naturalize by branching rhizomes if they are happy. In the wild it typically occurs on rocky, wooded slopes and bluffs.
