HARDY DUTCH IRIS COLLECTION Dutch iris are so popular as a cut flower that millions are grown in California and Holland to supply florists worldwide. We have assembled a special collection of all the best colors – not only blue and yellow (the two most popular), but also a rare bronze and a dazzling white, plus bicolors. Just plant in any sunny or lightly shaded area of your garden for an uplifting display that is likely to increase year after year. These Dutch iris are earlier flowering than bearded or Siberian iris. They are also longer lasting as a cut flower.
