On this website you will find a basic guide to the family of irises. We have also added links to the wide range of other sources that we hope you may find interesting and useful.

Information about the BIS is here as well as lists of its events and related groups, both local and specialist.

We hope you will enjoy this site and come to share our love, excitement and interest in Irises.

Note that our membership rates have now changed but still offer excellent value, new members will be welcomed and enquiries through the contact page answered as promptly as possible.

Promoting British Irises since 1922

Become a member of the society

Our membership grows a wide range of plants and it is often said that there is an iris for every soil condition.

Some members also continue the long tradition of breeding new varieties while others work hard to preserve historic ones.

The BIS counts a number of Plant Heritage National Collection Holders amongst its members.
