If you're making them out of fondant/gumpaste then an easy way to do the stamen is before making the flowers shape a long thin cone shape with a slight curve and let it dry. When dry dip the end in edible glue and then dip in yellow/gold nonpareils and let dry. They turn out looking like these (may not be the look you want, but for a less formal cake they look fine):

and these (although I think I made the stamen a little too thick on these ones) http://cakecentral.com/gallery/1814953
