I found a couple pics on google. The english name would certainly provide
more, but I don't know it.

I do not have experience, but I can tell you how I would model the flower. I
am going to assume that you want to model a very detailed flower.

I would first make a 4 splines to represent the sides, top, and bottom curve
of each petal. I would then adjust the control points on each spline until I
got the shape that I wanted for these curves.

I would then make a 3 dimensional mesh using points on the four splines to
build the spline, putting at least 10 columns of vertices along the top of
each petal.

I would then find the normal of each vertex and translate the vertices along
these normals by an amount represented by a sin value. This value should be
scaled down along the edges of the petal and will give the ridges in the
petals.

My next step would be to put all of this into a macro which would change the
control points of the splines very slightly each time a petal is created so
that all will be unique.

As far as the center, I would have to see if a union of tiny objects would
be faster and close enough in quality to an isosurface distorted by a map.

Hope this helps.
