01 - In a small saucepan, combine water and sugar. Bring to a simmer over medium heat, stirring until the sugar is dissolved. Remove from heat, stir in dried lavender, and let steep for 15 minutes.
02 - Strain the lavender from the syrup using a fine-mesh sieve. Allow the syrup to cool completely before mixing with lemonade.
03 - In a large pitcher, combine lemon juice, cooled lavender syrup, and cold water. Stir thoroughly until well blended.
04 - Taste and adjust sweetness or tartness by adding more water for a lighter flavor, additional syrup for sweetness, or extra lemon juice for tartness as preferred.
05 - Add ice cubes to the pitcher. Pour over ice-filled glasses and garnish with fresh lemon slices and lavender sprigs if desired.
