Silver flower fragrance (single cluster), commonly known as Yashixiang(鸭屎香), is produced in Chaozhou, Guangdong. It is a fragrance type of Pheonix (single cluster) tea. It is named because the tea leaves are planted in "duck droppings soil" (yellow loam) and the shape of the tea leaves resembles duck foot wood. At present, Yashixiang(鸭屎香) is widely used in the tea industry
Hand-mixed Lemon and Silver Flower Fragrance Tea
Since Yashixiang(鸭屎香)is a more commonly known name than Silver flower fragrance (银花香), the tea companies use it to avoid confusion, people who know 鸭屎香 might not know it is also called 银花香
As for marketing, since everyone associates 鸭屎香 with a particular fragrance instead of duck poo, there is no major issue, on the contrary, it is a more memorable and catchy name compared to the fairy bland "Silver Flower Fragrance"
