Heat olive oil in a skillet over medium heat. Add garlic and shrimp and cook halfway through (about 2 to 3 minutes). Add salt, pepper, white wine and lavender and turn heat to high. When mixture boils, remove shrimp with a slotted spoon, leaving pan juices. Add agave to pan juices and reduce mixture by three-fourths over medium heat until it will coat the back of a metal spoon. Toss shrimp and serve as an appetizer or entrée.
