    Rudbeckia fulgida "inside out"

    These are shots of one of the last Rudbeckia fulgida flowers I captured this year. Well what's so special about it? It shows what I usually do, photography in ultraviolet (UV) light, which is shown on the right side:

    Interestingly enough, this flower shows different types of UV reflection, but more about that later, as it is my 1st picture post and one need to gets used to "such stuff" first

    Fully blossomed it looks like that then btw. (studio shot):

    showing the typical "bullseye UV pattern" that guides bees to the nectar (henc callesd "nectar guides" and gives this flower a competitive edge over flowers that doesn't have such UV markings. Remember, bees see UV, blue and green whereas we humans see blue, green and red, but not UV (well most of us do).

    As I am an amateur taxonomist and my photography is primarily used for plant ID, I find your photographs extremely interesting. Although I am a little south of the range for Rudbeckia fulgida, we do have R. hirta in this area. Do you have a website where you post your images?

    Thanks, yes I have quite a few of R. hirta also, but mainly cultivars.

    Best would be to go to my BLOG and enter the plant name, "hirta" in that case, into the search field on the right side.

    Here is another one, that I believe to be R. hirta:
