One of the flowers which I had planted last year in a different plot seems to have bloomed in our raised bed from out of nowhere. There was one flower which looked freshly bloomed, which is why I just had to pick it to photograph indoors. If I don’t, then there will not be many more opportunities to do so as the flowering season is soon coming to an end.
In UV, the petals do have a greenish (rather than yellow) colour to them, which is why it shows up fairly bright in the 330AF20 image as well i.e. its UV-reflectance is in the deeper UV range.
