2 species from South Eastern Australia. Iris-like, with evergreen, sword-like leaves. Flowers smaller than irises, with three outer petals, white, rounded and the three inner petals, smaller and patterned. Attractive.
As is typical with members of the iris family, the fragrant flowers are insect pollinated, though we have few indications of the value to insects in this country, as opposed to their native Australia. As with all clump-formers they will provide useful shelter for garden insects, including beneficial predators such as ladybirds.
