Yeah, they are a 'stylized' dogwood. Since you have until May why don't you make them?
I don't have the cutters for them wherw can I find?
You can get dogwood cutters from pretty much any place that sells cake supplies. I'm sure Global Sugar Arts has them, sugarcraft.com does, Nicholas Lodge sells them... Where do you normally purchase your supplies from? The ones on that cake are gumpaste or fondant, but a royal icing primrose is basically the same shape if you wanted to make them. Good luck.
