Japanese Iris (formerly I. kaempferi) bloom in June and July, well after most other Iris have finished blooming. In the border, their rich colors and elegant form add a whole new dimension. Japanese Iris require full sun (partial shade in the South) and rich, acid soil. They prefer constant moisture during the growing season, well-drained soil in winter. Plants perform best if they are divided every 3-4 years. Winter protection is advisable in exposed places in Zone 4. Not suited to the dry heat of the desert Southwest.
