Combine the sugar, water, and lavender in a medium, heavy-bottomed saucepan.

Bring to a boil on high heat, and boil for 1 minute.

Remove from the heat, cover, and let the lavender steep in the syrup for 20 minutes.

Strain through a fine mesh sieve to remove the lavender, and add the food coloring if using.

Set the syrup aside to cool.

Once cooled, place the lemon juice, sugar, coconut water, and water into a pitcher and shake or stir vigorously until all the sugar is dissolved.

Pour 1/2 of the lavender syrup into the pitcher and stir. Adjust syrup to personal taste.
