Modelling of a curve in 3D space

[ann96]

i'm looking for a curve that would have a shape of a snowdrop (the white spring flower) in 3D space. i have tried some sine and cosine functions but they don't give me the right shape. if anyone knows how solve this problem feel free to comment :)

(i have tried f(x,y)= sin (x*x + y*y)/(x*x + y*y) ...but it gives me more of a water drop shape.)

Perhaps you can give us more information about what you're looking for?

in the first attached file is the curve i was talking about and in the second file is the curve i would like to get and is similar to a snowdrop (on the picture)
