In a small saucepan, combine 1 cup sugar, 1 cup water, and 2 tablespoons dried culinary lavender. Bring to a boil, then reduce heat and simmer for 5 minutes. Remove from heat and let steep for 10-15 minutes. Strain the syrup through a fine-mesh sieve into a jar, discarding the lavender. Let cool completely.

In a large pitcher, combine the fresh lemon juice, 3 cups of cold water, and 1/2 cup of the cooled lavender syrup. Stir well to combine.

Taste the lemonade and add more lavender syrup if you prefer a sweeter or stronger lavender flavor. You can also add more water for a less concentrated drink.

Refrigerate the lavender lemonade for at least 30 minutes to ensure it's thoroughly chilled.

Serve the lavender lemonade over ice in individual glasses. Garnish each glass with a slice of fresh lemon and a sprig of fresh lavender.
