Beautiful, and great observations all! Agreed. I love this one!
In 2022, here it bloomed 6/12, instant rebloomed (just as fully as the first round) with a rebloom peak at the end of July, and was still going until early September! It set only a few pods. I have had much better success with pod fertility when it was in a midday shade situation in its former spot, but increase suffered because of the shade. Here's a picture from 7/2/2022, showing an instant rebloom scape towards the front.
It makes stunning children, very dominantly flat and yellow with good substance and texture:
