"Purple Heart" plant. So easy to grow! Comes back year after year. You can easily divide this plant by pinching off a clipping where it forms a "V" and transplant in rich soil. Makes a beautiful border!
'Gerald Darby' iris (Iris x robusta): some of the foliage and the stems are purple. It's a siberian iris, so no beard. Flower is also purple. Tubers on eBay.
