In a large jar, combine the dried calendula and blue butterfly pea flowers.
Cover with coconut oil and secure the lid.
Let the oil infuse at room temperature in a dark place for at least 1 week, and up to 6 weeks.
Strain the flowers from the infused oil, then proceed with making the candles.
In a double boiler over medium heat, add the infused oil and soy wax flakes.
Stir until melted, about 5 minutes.
Turn off the heat and add the essential oils.
Place the wick in your heat-safe container, securing it with a wick holder or by threading it between chopsticks resting on top of the container.
Pour the melted mixture into the container, then immediately sprinkle with crushed dried calendula and blue butterfly pea flowers.
Allow it to cure in a cool, dark place for at least 4 hours.
Once set, trim the wick to about 1 inch before lighting and enjoying.
