I have both "pink" pudica and the white and the "pink " has like Hetty said 90% of the pink is located on the back of the flower! iT IS MORE FRAGRANT but is doesn't have the different leaves and they don't bloom as long the flower is nice. I have several from Thailand grafted and a few cuttings and the cuttings are NOT as easy to root and I do not see the BUSH that they Bridal pudica will create,
this is one of my blooms
