Aril and Arilbred irises take their name from the small white attachment to the seed – the ‘aril’. Aril bred irises are formed by intercrossing the aril species – the beautiful oncocycli with the more hardy regalia species, or by crossing these further with bearded irises. The aril genes contribute to the unique colouration, form and beauty, while the bearded iris genes give greater garden hardiness, and increase bloom count to the plants.

Arilbred Iris "Loudmouth"

Coming from the desert regions of Eastern Europe and Asia, Aril irises are dry ground plants, and only tolerate moisture during active growth in Autumn and Spring. They and their hybrids need to be grown in very well drained soil, and sheltered from Summer rains.

Early hybridiser William Mohr registered quarterbred varieties such as LADY MOHR, ORMOHR and ELMOHR, which may grow as well as Tall Bearded irises, needing just a little more attention to drainage and feeding. Australian hybridiser, Sam Fankhauser introduced a number of lovely Arilbreds in his lifetime, some of which are still available from growers. Varieties to try include AHMID BEY, NAOMI OF MARA, BEN HAROUN. Blooming early in the season, with the Spring bulbs, these irises may suffer from late frosts in cool areas. For enthusiasts, try growing these beauties in pots in a well draining gritty mix. Pots can be moved to shelter plants from frost and rain, and can be regularly fertilised. Allow plenty of sun during Winter and Spring, to ensure blooming, and to avoid overly tall stalks.
