If making the syrup fresh, simmer 1 cup sugar, 1 cup water and 1 tablespoon dried lavender buds over medium heat for 5 minutes, until the sugar dissolves.
Remove from heat, strain out the buds, and let the syrup cool completely, about 2 hours in the fridge.
Fill a tall glass with ice cubes.
Pour in the lemon juice and the cooled lavender syrup and stir until combined.
Top with cold water or sparkling water.
Garnish with a lemon wheel and a small scatter of dried lavender buds on top.
Good to Know
The syrup keeps in a sealed jar in the fridge for about two weeks, so make a double batch once and pour this in under two minutes all month.
