01 - Combine water and sugar in a small saucepan. Bring to a simmer over medium heat, stirring constantly until sugar completely dissolves. Remove from heat, stir in dried lavender, and let steep for 15 minutes to infuse the floral flavor.
02 - Pour the lavender mixture through a fine-mesh sieve to remove all lavender buds. Allow the strained syrup to cool to room temperature before using.
03 - In a large pitcher, combine the fresh lemon juice, cooled lavender syrup, and cold water. Stir thoroughly until all components are well blended.
04 - Taste the lemonade and modify the flavor balance as needed by adding more water for mellowness, additional syrup for sweetness, or extra lemon juice for tartness.
05 - Add ice cubes to the pitcher. Pour over ice in individual glasses and garnish with fresh lemon slices and lavender sprigs if desired.
