This fascinating little iris, native to the Caucuses, is little-known outside Europe, where it has been awarded the prestigious Award of Garden Merit (AGM) by the Royal Horticultural Society. The narrow foliage makes a tight upright clump to 15" tall. In June, the purple narrow-petaled flowers are nestled down in the foliage. Despite not being able to see the flowers without parting the leaves, the fragrance, which has been described between grapes and plum tarts, is certainly evident. An open, slightly moist site with acid-to-neutral soils seems to be preferred.
