Iris Crossiris section (crested irises)

This is a group of just a few species, from the eastern Himalaya to Japan, characterised by a comb-like structure on the falls. The species in one of the series that make up the section, notably Iris japonica, are not completely hardy in the UK, but the other series, consisting of Iris milesii and Iris tectorum, are completely hardy. All have lots of flowers and are good garden plants.
