The Dutch iris is a perennial flower that blooms on long, straight stalks. The flower comes in a number of colours, including shades of blue. Like most perennial flowers, the blue Dutch iris thrives in well draining soil that gets full sun. Once you select your site, planting the flower and caring for it is simple.

  1. 1

    Select a site for your flowers. The site should have good drainage and receive eight hours of sun daily. If the ground holds puddles of water six hours after rainfall, select a different site. Select your site in the early fall.

  2. 2

    Remove all weeds from the site by pulling them up by the roots or digging them out with a hand spade. Do not compost weeds or you will spread the seeds with the compost.

  3. 3

    Spread a 2-inch layer of compost over the site and turn it into the soil with a garden tiller at a depth of 6 inches.

  4. 4

    Dig a hole 4 inches deep and insert the bulb with the pointed end facing upwards. If you have more than one bulb, plant them 3 inches apart. Firm the soil over the bulbs and water until the soil settles. The bulbs will sprout in the fall or winter and the flowers will blossom the following spring.

  5. 5

    Water often enough to keep the soil moist to the touch. This frequency will vary with your climate. Remove any yellow foliage during the summer and do not water during the summer when the plant is dormant.
