Hi Island Girl - Thanks for your continued interest! Yes, it's certainly a Colmanara Wildcat as the wisdom of OB had decreed.
I'd been waiting for her to finish opening for a photoshoot, but you inspired me to go for it today!
I can't detect any scent from the flowers at all (though not normally known for my keen sense of smell).
I've been just letting her do her thing with minimal care and maximal observation.
Part of me wants to delve further for some concrete ID, but I'm pleased enough to call it "Wildcat" and admire.
(although 'Everlasting' looks pretty close...)
Thanks again everyone!
