The Iridaceae contains many hundreds of attractive species that have been overlooked for horticultural development. The incredible variation in flower and leaf shape, size and colour suggest this little-tapped resource could offer great opportunities for developing new commercial ornamental products. Micropropagation has increasingly become a valuable tool assisting breeders to release new species and cultivars into the market more rapidly. Here we review the progress made in Iridaceae micropropagation genus by genus, and highlight the potential for future expansion in this field.
