Rare Treat: Beautiful, Fragrant and I've had it Rebloom.
I actually had it bloom the week of Christmas, it had been mild weather, nothing below 33*F, then the day after Christmas temps dropped to 20* and it died, May Rebloomed.

This has got to be one of the most beautiful Iris's I have ever seen. I bought it as a young plant...and it has been in the ground for between 3 & 4 yrs now. It has done nothing but increase in size and beauty every year! Originally plant was 1-2 fans....now the 'clump' is nearly 4ft across! I'm sure I'll have to divide it sooner or later...but it's doing so well I hate to disturb it. Really increases fast. Have done nothing special to raise this plant what so ever. Clay soil ammended with peat moss.
