I have 2 beds for my Iris and also some wild iris on a small hill. My background of the largest bed are re-blooming White iris. I do not know the variety. A gift was made of them to me. This is the third year of re-bloom on these white ones ( including "Immorality") and in the spring I will be dividing this bed as the rhizomes have really gotten big. In front of the whites I have mostly dark purple Including Night Owl, Midsummer Night Dream, Night to Remember, and light purple Fogbound. As accent I have Day Glow, Don't Touch, Amber Gleam, Extreme Orange, Devils Riot and finally Fire-breather.
In the smaller bed, I have only a couple of the same unknown white RB, and this is where I planted most of my orange and rose colored iris, Lady Friend, I also have pastels Halloween Halo, Champagne Elegance, Chasing Rainbows. (planted this fall)
Boss Tweed, Jealous Halo, Lady Fire, Paninoforte, Tennison Ridge, Wise Wish, King Tush, and Rock and Roll Girl. I have had Great Luck with the Iris in this bed. I Can hardly wait until next year.
