The official state flower of Nevada is the sagebrush, which can grow to an astonishing 12 feet in height. The closest I can come realistically with royal icing is a handful of sprigs, which would make a cute garnish on any desert-themed dessert. All you'll need are stiff-consistency royal icing in yellow and green, round tip #4, a flower nail, a Styrofoam block, a glue stick, parchment paper squares, and a dusting pouch filled with a 50/50 mix of powdered sugar and cornstarch. Start by sticking a parchment square to the flower nail with a dab from the glue stick.
royal icing rattlesnake; a good companion animal for the sagebrush!
