There are many versions of iris, but the two selections that are best suited for area landscapes seem to be the cemetery iris and the bearded iris. The cemetery iris are the plants that seem to survive and bloom on every old homestead and cemetery. They have blue or white flowers that appear in February or even January some years. They make the best groundcovers, because the blades are shorter and they provide a more dense cover.
Bearded iris are the big plants you see blooming in April with large orchid like blooms of white, yellow, blue, purple, maroon, salmon, brown and many bicolors. Many have very pleasant fragrances.
November is the best time to thin iris beds so it is an ideal time to score the extra rhizomes that are removed from the gardens of friends and neighbors. Retail nurseries also sell rhizomes now through the spring. They can also be purchased as container plants. The advantage to purchasing the container plants is that they will bloom the first spring. They rhizome planted iris may also bloom the first spring, but it is less certain.
New beds should be located in full sun. Iris respond to soil enriched with two inches of compost and a cup of slow release lawn fertilizer incorporated into every 50 square feet of the bed, but they are not fussy about soil. Plant the rhizomes so that the top surface is level with the soil surface. Iris rot if they are planted too deep. Iris are also one of the few plants that do not seem to benefit by mulch.
