Iris spurias do not like to be disturbed; keep them in the same place for a number of years. Because their height is 3-5′; they are usually planted in the back of a bed or along a fence. They are ideal vertical accents. Plant rhizomes 1-2″ deep, with good drainage. Heavy watering in spring will increase growth and bloom. Cut foliage to the ground in late summer. New growth will start in the fall or spring. They are not affected by serious disease except crown rot (fungus), which is hard to eradicate. The flowers are long-lasting and great in flower arrangements. Sold bare root.
