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 flavors.
02 - Pour the lavender mixture through a fine-mesh sieve to remove all lavender buds. Transfer the strained syrup to a heat-safe container and allow it to cool completely before using.
03 - In a large pitcher, whisk together the fresh lemon juice, cooled lavender syrup, and cold water until fully combined. The mixture should have a pale pink hue from the lavender infusion.
04 - Sample the lemonade and modify the balance as needed. Add more water for a lighter flavor, extra syrup for increased sweetness, or additional lemon juice for more tartness.
05 - Fill the pitcher with ice cubes. Pour over ice in individual glasses and garnish with fresh lemon slices and lavender sprigs if desired. Serve immediately while chilled.
