Welcome to our new website! 

We hope you enjoy exploring our site to learn more about irises and The Iris Society of Australia.

Scroll down to see what's here, or use the menu along the top. Note - we have jammed so much iris information on to this site you'll have to use the "more" button from the top menu to see all the menu items. This site includes information on types of iris, what will grow in your area, how to divide your irises, how to make your own iris crosses (hybridising), anatomy of an iris flower and plant, iris terms and abbreviations, and more! The site will be updated regularly so check back often to see what's new.

Like and follow The Iris Society of Australia on facebook to be notified of updates.
