I have a few. Most of them are white, but some do have coloured beards. Unfortunately, because most of them are all new, I can't say much about them.
Mesmerizer - It was planted in a relatively shady spot in 2018 and has sent up two, or three increases. I am really looking forward to this one inparticular.
Nordica - Of three rhizomes planted in 2018, one exploded in green (four or five increases!). The other has one increase growing, and the third I am only seeing a fan still. The third has had a hard time it seems.
Arctic Express - Two rhizomes. Both are doing well! A truck ran over both of the rhizomes along with a few noid others (and narrowly missed smushing several other ID irises). As far as I can tell, they seem to be rebounding. Do not know if any increases were lost.
Florentina (Iris Germanica) - The database says light blue, but I see more white than I do blue. Either way, this oldie has sent me up three increases. I am hoping to see it bloom!
--Not fully whites--
I'll include my own little snippet of "whites" that I have that aren't selfs.
Gay Paree - Of all the irises I have obtained, this is one I believe is one of my noids, which HAS bloomed. If it pays true, this cultivar has bloomed sporadically. Say, 2/5 years. I've transplanted a rhizome (noid) to a sunny spot in hopes it will thrive well. The ID version is next to....
Gay Pal - Which is another attempt to ID the noid. Based on the two database pictures, and the lesser known stature of this iris over Gay Paree, I feel that Gay Paree has a better chance to be the noid over Gay Pal.
There's quite a few white selfs or lightly splashed colours on white irises that I'd love to have some day. Probably the #1 spot goes to Immortality. I want to utilize the iris' reblooming ability if I can in crosses!
Thank you for the thread, Evelyn!
