The first version of IrisBG was developed by Øyvind Rustan in 1996 in close collaboration with the Botanical Garden, University of Oslo (Norway). In 2004, version 2 was introduced and successfully adopted by the majority of botanic gardens in Norway. In 2007, Botanical Software Ltd was established in the UK to offer IrisBG to the global market. Version 3, introduced in 2010 based on the sister product Corema, was a full redesign and substantial upgrade of IrisBG that offered support for multiple collection sites, zoological or botanical nomenclature, preserved and living material, integrated mapping, report customization, data import, custom fields, and much more. Since 1996, IrisBG has been carefully curated in close collaboration with the community and is, arguably, the most comprehensive integrated software solution available for botanic gardens today.

The system is distributed by Digital Forvaltning AS (Norway) and Botanical Software Ltd (International).
