rarest species, on the verge of extinction. One of the most adaptive populations was found in nature VM Doronkin, reproduced in Novosibirsk botanical garden. The peculiarities of foliage and short peduncles reminds iris Pontic. In the wild flora iris Ludwig found predominantly in dry gravelly soils of shrubs and tall-feather grass. In a culture still poorly tested. More promising for cultivation in the dry steppe regions. Interesting as a component when hybridized with iris Pontus.
Tested in Barnaul, Novosibirsk, St. Petersburg, Chita. In the culture is not stable, not infrequently after flowering dies tying bad seeds. Good for rocky hills and curbs.
