In a small saucepan, combine 2 cups of the filtered water with the dried culinary lavender buds. Place the saucepan over medium heat and bring the mixture to a gentle boil. Once boiling, reduce the heat to low and let it simmer for about 5 minutes to infuse the flavor of the lavender.
After 5 minutes, remove the saucepan from heat. Add the raw honey to the lavender infusion. Stir the mixture thoroughly until the honey is fully dissolved, creating a smooth syrup that combines the floral lavender flavor and sweetness.
Using a fine mesh sieve or cheesecloth, strain the lavender syrup into a bowl to separate the lavender buds from the liquid. Allow the syrup to cool to room temperature.
In a large pitcher, combine the freshly squeezed lemon juice with the 4 cups of cold filtered water and the cooled lavender syrup. Stir well, ensuring that all the flavors meld together beautifully.
Taste your homemade lemonade and adjust the sweetness to your liking by adding more honey if desired. Stir again until the honey is well blended into the mixture.
Serve the refreshing lemonade over ice cubes in tall glasses. To enhance the presentation and aroma, garnish each drink with a slice of lemon and a sprig of fresh lavender.
