Cultivars of Iris sibirica
International Cultivar Registration Authorities (ICRAs) are encouraged to keep databases of registrations which can then be searched online. Online registers are becoming more available. They are an excellent way of disseminating information to the widest possible audience.
However, as the Registers and Supplements are often the only valid place of publication, hard copies still need to be printed to ensure new names are validly published.
Many ICRAs are seeking to establish an entirely online registration process, but most, at present, require forms to be filled in and either emailed or posted to the Registrar.
Below are listed links to Cultivar Registers available online .
