Arilbreds (AB) are hybrids of Aril, Onco, and Regalia species of the Middle East, crossed with bearded irises. They have greater cultual tolerance than the pure species. Plants tend to go dormant durning the hot, dry summer. They range in height from about 4" to 48", so watch descriptions! Prefer well-drained soil. Top awards for this class: CGW (C.G. White Medal), ½ or more Aril. WMM (Mohr Meal), ¼ to ½ Aril.
