Not much help here either, but I have 'Beautiful Edgings' and 'Brocaded Gown', though the deer keep getting the latter.
'Beautiful Edgings' is
beautiful, and has thus far proved very rust resistant. The downsides are that the edge is photosensitive (so I advise planting it in morning shade), and for me, the sepals don't necessarily curve under properly by themselves; they kind of kink a little. That means that every morning when the plant is in bloom, I have to go out and poke and prod the sepals into shape. (Well, I don't have
to, but if I want the blooms to look their best....) I don't know if this sepal behavior is a quirk of the plant, or some artifact of dry soil, or pertains to our climate, or what.
I have 'Beautiful Edgings' planted next to a red maple, where it gets morning shade and it looks very good there (the faint color on the bloom edge echoes the red foliage of the maple, at least while the blooms are still shaded). You may want to consider some similar placement.
As for 'Brocaded Gown', my recollections from when I last saw it in bloom (literally years ago) are that it is indeed a beautiful flower. Supposedly the plant is rust resistant, but it is in a part of the garden where it has had little exposure to rust, so I cannot verify that.
I have to say that my problem with 'Brocaded Gown' is that the scapes are short; I don't think that I have ever seen them make it to 26". (Maybe that is due to our soil or my neglectful cultural practices...
) I have it placed in a bed atop of/behind a retaining wall, right along the edge, so as to give it a proper height and close-up location for my viewing pleasure.
FWIW, I obtained Tetra 'Brocaded Gown' from the Lily Auction earlier this year. It is in a pot and is now sending up bloom scapes, and I have caged the plant in hopes of fending off the deer. It is already too slow to bloom to cross it with the plant that I bought it to mate with (unless I remember to save pollen off the last bloom of that plant, assuming that I haven't already missed that bloom (it's been a busy few days)).
But I am anticipating the blooms on this tet conversion nonetheless.
Edited to correct grammar, and also to add that the blooms on 'Brocaded Gown' have a crepe texture. This may or may not be a deal killer for you, but I thought that I ought to mention it, in case you missed it. (You can see the crepe texture on the images in the database.)
