Ha! most of my favorites are NOIDs too.
Possibly 'Classic Look'.. goes with everything, always beautiful.
Two blue rebloomers from a dear friend who is no longer with us.
'Quaker Lady'
Iris pallida 'Aurea Variegata'
'Mulled Wine'- just a great color
'Competitive Edge'- one of the last to bloom & looks great w/ purple foliage plants
I'm sure there are more.... There are many that are newer that look like they're going to become favorites.. I'll need a couple more years to evaluate, but if these continue as they have , I might add: 'That's All Folks', 'Conjuration', 'Spring Bliss', 'Alcazar', 'Spooned Blaze', 'Confetti', 'Fall Fiesta', 'Dynamite', 'Whole Cloth', 'Easter Bonnet', 'Paul Black', 'Absolute Treasure', 'Splashacata'....
If I ever move to a small yard, I'm toast...
