Also known as twelve apostles, walking iris are herbaceous perennials that grow to a height of 1-1/2 to 3 feet. They bloom off and on in spring, summer and fall, producing small, iris-type flowers and grow best in partially shady sites where they get four to six hours of direct morning sun or in dappled or bright shade. Can be planted in loamy, sandy or clay soils but prefer it somewhat acidic. Keep soil moist for a few weeks when first planted and then water once a week, more if leaves appear wilting.
