Passion flower - weird or what?

Look at the thing - it's like from another planet.

The first layer is nine big green/white petals.

Then a small yellow circle with a ring of spikes that start purple, go white in the middle and are then blue-ish at the end.

Then a 3-D target on the yellow circle made up of a dotted black line and some pink/black spikes that point inwards.

Then a little green stick in the middle with five yellow things hanging downwards.

Then a little green ball on top of that.

And finally three droopy purple things on that look like antennae.

I plucked one of the flowers (it grows along my neighbour's side of the fence) and took it with me when I dropped the lad off at school, and the other parents agreed is was pretty weird.
