Combine lemon juice, sugar, and water in a large pitcher, stirring until the sugar is dissolved

Add dried lavender buds to the mixture and let it steep for about 10-15 minutes, or until the mixture reaches the desired flavor

Strain the mixture through a fine-mesh sieve into another pitcher or individual glasses to remove the lavender buds

Serve the Lavenade chilled, garnishing with lemon slices or sprigs of fresh lavender, if desired

Adjust the amount of lavender to taste, as some may find the flavor too potent
