Heat 1 cup of the water until it's very hot, but not boiling. Steep the lavender and hot water for 3-4 minutes in a covered container. Strain and cool the infusion in the fridge.
Add the honey, lemon juice, lavender infusion and 8 cups water to a large pitcher. Stir well until combined.
Serve chilled with ice and lemon slices if desired.
