Zhi Yun
The new tea cultivar Zhi Yun was developed under the number in 1992 from a cross with a large-leaf Burmese tea plant by the Tea Research and Extension Station (TRES) of the Council of Agriculture (Executive Yuan) in Taiwan. Following targeted selection of individual plants as well as comparison and characterization tests, it was officially named on April 26, 2021, and was granted plant variety rights on June 6, 2022.
Genetic analyses show that “TTES #25” combines traits of both large-leaf and small-leaf tea plants, and it is closely related to “TTES #13”, Cui Yu. The alignment of specific gene markers indicates that “TTES #13” is likely the male parent.
“TTES #25” is characterized by a semi-arboreal growth habit, vigorous development, and purple-red young buds and leaves throughout the year. It is the first purple-bud variety in the TTES series and has an anthocyanin content approximately 50 times higher than that of “TTES #18.” The leaves have a floral aroma and are suitable for both black and green tea, with the latter exhibiting a slight violet hue. When added to acidic beverages, the infusion turns a vivid pink, making this cultivar particularly appealing for creative beverage creations.
Beyond its use for tea, “TTES No. 25” also offers ornamental value in gardens and landscapes due to its purple-red foliage, thus combining both aesthetic and culinary benefits.
