Despite the tongue-twisting name, which means "bright inspiration," we really enjoy this bizarre cross of Iris pseudacorus x Iris ensata. While it grows well in shallow water, we grow ours in dry sand where it is equally wonderful. The deer-resistant foliage emerges chartreuse-yellow in spring, highlighted by the large flowers in mid-May (NC). Each hummingbird-attracting flower is light yellow, topped by an attractive brown marking near the base of the petals. As compared to the prolific-seeding Iris pseudacorus, the best feature of Iris 'Aichi no Kagayaki' (my #@x@x* spell checker keeps insisting on Kawasaki) is its sterility...no garden abortions necessary.
