Fill a small saucepan with water, about two-thirds full.
Add the fresh rosemary sprigs, lemon slices, lime slices, lavender buds, and mint leaves.
If you're using lavender essential oil, add a drop to the water instead of lavender buds.
Place the saucepan on your stovetop over low heat.
As the water begins to simmer, the delightful scents of a blooming garden will permeate your space.
