I've seen that there are many daylilies with Siloam in the name. Is this a hybridizer? From where does this name originate?
That's a good question. I don't know the answer. You might ask on the daylily forum, if you don't get an answer here.
Here is a link that might be useful: Daylily Forum
The name comes from the hybridizer who was from Siloam Springs, AR.
