How elaborate a flower? Unrealistic daisy is simple. Realistic rose much
more difficult. At least from what I'm thinking it would be.

The daisy could be a radial pattern, like so:

function {
 pattern {
  radial
  scallop_wave frequency 6 // shape and number of petals
  rotate 90*x
 }
}

Then used as:

isosurface {
 function {
  (x*x+y*y+z*z) // sphere shape
  -
  FlowerPattern(x,y,z)
 }
 contained_by {
  box {<-1,-1,-0.1>,<1,1,0.1>} // middle slice
 }
    pigment {
        spherical
            color_map {
                [0.75 color rgb <1,1,1>]
                [0.8 color rgb <1,1,0>]
            }
        }
}
