Add all ingredients, with plain ice cubes, in a cocktail shaker. Shake and strain over flower ice cubes. Top with a splash of ginger beer.
To make flower ice cubes
In an ice mold, lay pansies, babies breath, and green buttons. Gently pour water* over the flowers and freeze. Use plastic molds so the ice will be easier to remove.
Note from Amanda: For the clearest ice cubes, I like to use distilled water that I've boiled and cooled to room temperature. I also like to fill the trays incrementally, as described in the blog post above.
