Think of the difference that presentation makes for a meal. A delicious food choice thrown haphazardly onto a plate is not as enjoyable as a plate that is arranged for beauty. With blooming teas, artisans will take tea leaves and tie them together with a cotton cord in order to make a flower. Flowers are then dried for storage and shipping. When you add boiling water, the flowers are brought back to life.
You will take the small grayish ball of blooming tea and add it to a pot. Cover it with boiling water. There in your tea pot a beautiful flower begins to bloom. It is like a lifeless ball of tea comes to life as a blooming flower. That flower can add beauty to the table.
