How long have these teas existed?

The concept of display tea is an ancient chinese art that has existed for thousands of years. Teas were often used to visually entertain the emperor himself but were not drinkable. Hand sewn flowering teas you can drink are a more recent creation, dating back about 20 years. The Chinese prize them for their quality and enjoy them especially when friends and family gather for a very special occasion. It's only in the last couple of years that western countries have started to discover them. Their relative scarcity has made them quite difficult to obtain in many countries so many people have yet to experience the magic of seeing their first blooming tea.
