These are hardy, damp-loving irises, widespread in the Northern Hemisphere. They make spreading mats of rhizomes, and flower best if planted in sunny places, so long as the dampness, or even wetness, is ensured. They include our British native flag iris.

Iris prismatica is a North American species, with clumps of grassy leaves and clusters of two or three flowers, violet blue but attractively veined in deeper purple. It is actually in a series of its own (Prismaticae), but it is close enough to the Laevigatae for us to include it and give it some company.
