Combine 1 cup of water, sugar, and lavender in a pot or saucepan. Heat to a boil, reduce heat to low, and simmer until all of the sugar is dissolved. Let rest for 2-3 minutes. Strain out lavender flowers and set the syrup aside to cool.
Pour syrup, lemon juice, and remaining water into a pitcher. Stir to combine.
Serve over ice. Enjoy!
