To prepare the base drink, boil ½ cup of water in a saucepan and transfer it into a teapot. Place the passion tea bag in the teapot and let it steep for about 5 minutes, then transfer the passion tea into a pitcher.
Boil the remaining water and transfer it to the teapot; put both hibiscus and green tea bags in, and let them steep for about 5 minutes.
Pour the hibiscus tea into the pitcher and mix the two teas gently.
Add all the other ingredients into the pitcher, except ice cubes and frozen berries, and stir thoroughly until perfectly mixed.
Let the mixture cool to room temperature.
Fill about ¾ of two glasses with ice cubes and frozen berries and then pour the cooled tea over; garnish the drink with lime wheels and enjoy.
