This lily is definitely not Tiger Babies, which I already have. This is a pale golden tan with a bit of pink flush, and it does not have the deep purple reverse like TB.
Buff lily:



Tiger Babies for comparison:

Also buff lily's flowers are held more horizontally and are less reflexed.

About 30 inches tall.

Did you remove the anthers or is it naturally pollenless?

I did not take the anthers off. Good catch.

No pollen means collecting seeds is not likely to give me identical plants, I guess. It's mixed in with Forever Susan or something similar, and I'm hoping I can contact the homeowner, and that he/she will share.

It's a persistent plant, lasting 20 years in that spot with not much care, but the Forever Susans might be crowding it.

I thought it looked like an older cultivar, perhaps from a Canadian hybridizer. It might be difficult to identify it unless someone here recognizes it as something they too have grown.

Lilies in general can't self-pollinate but pollen from a different Asiatic might be able to pollinate it. You might for the fun of it give it a try with your Forever Susan like lily. I don't believe Tiger Babies would work because I believe it is triploid but older garden lilies are diploid.
