I have a whole bunch of frozen pollen, too. It was a good thing, too, because otherwise I'd have nothing to attempt to pollinate my Heavenly Angel Ice with. (Although I'm really wondering if any of the seedpods on it will even make it to maturity before frost starts killing everything off.)
...and if it were for being able to freeze pollen, I also wouldn't have anything left of my beloved Titan of Ice, which I'm REALLY hoping makes a comeback next year. I'm resisting the urge to dig it up and see what the roots look like right now since I moved/replanted it about a month ago to give it a better growing spot.
Anyway, though, that bloom of Viva Las Vegas looks beautiful. Funny, too, that my family is in Las Vegas at the moment.
