This iris, with yellow and maroon-striped flowers, has been growing for decades on the property that became the Jensen-Olson Arboretum. Gracchus is believed to have been brought over from Germany by Marie Peterson in the late 1800s. It blooms well in the cool, wet maritime climate. Garden irises are hardy, long-lived perennials that need reasonably good, well-drained, moist soil, and full sun. When planting, dig a hole large enough so that the rhizome will be covered with about an inch of soil. Leave a slightly raised mound in the center. Place the rhizome on the mound with the roots spread on either side. Cover with soil and water thoroughly. Divide when plants become crowded. Parts of plant are poisonous if ingested. Handling plant may cause skin irritation or allergic reaction. Clumps spread readily, perennial.
