Thank you all for your feedback!
I was able to go back through my pictures and it looks like the scapes are mostly 2 branches, maybe one had 3 way branching. It looked like each branch had about 6 flowers. Neither of these are addressed in the data base here.
I feel pretty confident that this is South Seas. Will definitely get out and measure it this summer. I did some major garden renovations last fall and weeded out all of the cone flowers, black eyed susans and other stuff that was invading the garden and trying to squish out the day lilies, so I should be able to get a good idea this year on size, etc.,
