I agree that most of these pictures are not of fractals.
I would add the lily pad, thinking cactus, cabbage and fern to the list of fractals. There are only a couple of octaves/iterations in each but there is some self similarity there.
Otherwise there are probably just a lot of Fibonacci spirals(although I haven't counted them).
For more on Fibonacci spirals see this[1] excellent video series by Vi Hart.
