I took another look at these this evening and 2 of them resemble irises (or is iris the plural form too?) that I have. I know it's a long-shot but here goes:
Tag 20 resembles Dutch Custard:
2008, Van Liere
'Dutch Custard' (Robert Van Liere, R. 2008). Sdlg. 99BT9. TB, 35" (89 cm), M. S. white, faint yellowing over veins; style arms white; F. white overlaid darker yellow; beards orange. 'Violet Dawson' X 'Satan's Mistress'. Tall Bearded Iris Society 2008.
and Tag 30 resembles Genteel, a rebloomer
1991, Byers
'Genteel' (Monty Byers, R. 1990). Sdlg. G39-111. TB, 34" (86 cm). Early, midseason, late bloom and rebloom. Heavily ruffled medium blue lilac; beards pale blue, tipped yellow. 'Eternal Bliss' X 'Pacific Tide'. Moonshine 1991.
Note: The color in my photos makes it look much darker that it really is.
I'll keep looking because I love a puzzle...but maybe this will be helpful...I hope!
