This stuff is free :-)
I only notice that NeptuneSuzy (http://www.thesimsresource.com/artists/Neptunesuzy/downloads/browse/category/sims2-body-accessories/page/2/cnt/38/) made some recolors of this flower mesh
http://www.thesimsresource.com/downloads/details/category/sims2-body-accessories-misc/title/MESH_DPXL011706FemaleHairFlower/id/257240/
and yes, they are pay. But only her (or his) recolors. Mesh is free. Besides Dr Pixel (he made this flower mesh) made some recolors and they are free to.
Oh and this stuff from Rose, Peggy and XM Sims is free to :-)
PS. Sorry for my English. I am from Poland
