This is so impressive. The flowers petals are trans-illuminated by the bright sunlight from behind shining through them. This alone makes flowers jump out so well from the background making that flower so much more significant. But the b.g., itself, is painted as by an impressionist - there are diverging rays of light and myriads of floating spheres of aberration.

.......and the softness of the bokeh makes the b.g. concede to the flower even more power.

This is a clear demonstration of how mistaken we often are in choosing lenses with uniform documentation of "everything" - illumination, detail to the corners, and b.g., save for planned fading outside the focus plane defined by pure optics.

Thanks Asher. I really like transilluminated flowers, as it is finally the light that
makes teh image, and it it just radiating. The sunrays in the images are
deliberately there as I wanted to make the light"visible"

Klaus,

Is the formation of such lines essentially the same as crepuscular light in landscapes, with the light breaking through cloud cover? What governs this? Is this red-green- blue particle scattering or yellow-red Raleigh scattering and are the rays color tinged?

Nope, this happens within the lens, diffration based on the glass lenses.
Hence if you know how that happens, it can be achieved at will,

"if you know that happens"?

But is this at your control? Or you know it might somehow occur and adjust the angle until it does?
