My guess is that they are made of gumpaste and are no particular flower, just "flower-shaped." You can use a small blossom cutter for the smaller ones. The big ones look like each petal was cut and then assembled with stamens or something to represent stamens.
I hope I die before "your" is the official contraction of "you are."
They are just made with a five petal blossom cutter , in different sizes. They could be made from either flowerpaste or fondant with tylose in it.
Very easy to make. The stamens are made from cotton by the looks of it. I use quilting cotton when I do this stiffened with just a little shortening to help them stand up.
