This is as close to registering a plant as I have gotten with my large dip UF's. About 7" flower, 47" tall this year, 2 branches with terminal Y, 16 bud count. Single much of the time, but also polys. I strongly suspect that it is out of Chartres. Substance that is not normally seen in a diploid UF, it is THAT leathery! Pod difficult, but pollen very fertile.
Frequently used as a parent for breeding, it has received some nice attention on my Lily Auction sales.:)
On maiden bloom each year, it has a tendency to poly, but doesn't for the rest of the year. I've been putting its pollen on polys in an effort to increase substance and variable form.
