In a saucepan, combine the fresh blueberries, dried lavender, and honey or simple syrup.
Add 1 cup of water and bring the mixture to a gentle simmer for about 5 minutes, crushing the blueberries slightly to release their flavor.
Remove from heat and strain the mixture into a pitcher, discarding the solids.
Stir in fresh lemon juice and add more water to your desired sweetness and strength.
Fill a glass with ice cubes and pour the blueberry lavender lemonade until it's about two-thirds full.
Top it up with still or sparkling water.
Garnish with fresh blueberries and lavender sprigs.
Sip and delight in the unique blend of blueberry and floral lavender in the refreshing lemonade.
