Objectives of the Species Iris Group of North America

The Species Iris Group of North America (SIGNA) is dedicated to the study of the wild species of the genus Iris and related irids in order to promote a wider appreciation of these plants and their hybrids as garden ornamentals. Our goal is to further their introduction and distribution through our seed exchange while supporting their conservation in the wild. We will disseminate scientific and cultural information about these plants to both our membership and the general public through our publication and such other means that may arise.
