Interesting, however...the irises referred to are actually "arilbred" meaning they are part aril. It is not technically correct to refer to these as "arils". Full aril irises would not be grown in most climates as it is a desert plant. By crossing arils with bearded irises you get a exotic looking plant that can be grown in most home gardens. I'm not even aware of any place I could buy a 100 percent aril iris. Most are 1/4 to 3/4 arils.

Superstition Iris Gardens sells at least one full aril iris, Turkish Topaz (a variety collected by Lloyd Austin). It grows and blooms quite well for me with no special care, unlike most pure arils.
