The large (almost 8″) flowers bear gently cascading petals in royal purple accented by flashes of white.
Japanese Iris (formerly I. kaempferi) flower 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.

HOW PLANTS ARE SHIPPED
The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.

Plant Japanese Iris in rich, acid soil. If your soil is alkaline, amend it with peat moss and periodically dust with sulfur formulated for soil application. Plants want ample moisture in summer but won't tolerate poorly drained soil in winter. Provide partial shade in the South. Divide after blooming or in fall every 3-4 years to prevent crowding.
