Absolutely stunning! The rigidus I had looked very much like that, except it didn't get as big. I'm not sure some of these Callistemons are named correctly, I've seen a so-called rigidus with very narrow leaves almost like pine needles.
The seed pods on mine just stayed on the stems for years! I would love to grow another but not sure it's worth the risk, my bumblebees and wasps used to love it!
We've had a very warm day here up to 25C, that's about my comfort limit but it was mostly cloudy.
