Irises can be used in borders, in informal groups in front of shrubs, in perennial beds or near ponds or pools. In some public areas they are displayed massed in curving beds for a stunning effect.
Container Gardening
Irises can be grown in tubs or standard clay pots. These should be 1 to 2 feet in diameter and at least 1 foot deep. It is essential that their soil be kept moist. See Growing Plants In Containers and Containers For Plants in Yardener’s Tool Shed.
Cutting Japanese Iris
Cut irises for indoor display in the early morning. Choose stalks with barely opened blossoms and cut them with a sharp knife. Add a half can of a citrus based soft drink such as 7Up or Slice to the water in the container in which they are arranged to prolong their freshness.
