Iris 'Kimboshi', which means "golden hat" in Japanese, is a 1971 eye-shadow hybrid of Iris pseudacorus x Iris ensata from Japan's Mr. Ueki. This sterile deer-resistant hybrid has amazing vigor and quickly forms a robust clump, topped in spring with large pale yellow flowers, each highlighted by a dark yellow eye-zone and dark lines radiating out into the three petals...delightful to hummingbirds. Iris 'Kimboshi' prefers moist soils but also grows well as a marginal aquatic. Thanks to the late garden writer, M.M. Graff, for sharing her favorite iris with us just prior to her death at age 97.
