Beautiful! I love it!

It truly is a beauty and I don't recognize it either!

Blue Curls I would say & a beautiful job of photographing them Fleur.

Rotheca myricoides

Lovely flower and photo, Fleur.
Could it possibly be Clerodendrum ugandense?

GrammaChar, Clerodendrum ugandense is now a synonym

Blue Glorybower (Rotheca myricoides subsp. myricoides)

Argggg.....the plant people keep changing the names, and I can't keep up with (or pronounce) the new ones! But thank you for the clarification.

Very sweet banner

One of my favorites! So very pretty, Fleur569.

Very beautiful banner! I grew these one year seems like I ordered them from a seller in Florida. They are such a different beautiful flower form anything else I ever grew. A friend in Florida grew them of course they grew much larger for her and even wintered outdoors.

When our local Target had a nursery, it carried this plant each year. It's quite tender and couldn't survive even a mild winter in our zone (9a), but I suspect that all of the stores in the Target chain carried the same plants with no regard for USDA zones. In spite of its fragility, I used to buy the plant each year. This beautiful banner reminds me why I paid top perennial prices for plants that could never be anything more than "annuals" in my garden.
