Overwintered buds sprout in the first ten days of March. The peak period of one bud and three leaves stage shoots appears in the first ten days of April. Plants wi th potent terminal growth rate and uniformly sprouting density. Shoots stout and light green in color, with rather profuse hairs and potent sprouting ability. The weight of 100 shoots with one bud and three leaves averaged 98.0~133.5 g. The peak period of flowering stage appears in the first ten days of November. Flowers larger in size, but low bearing capacity. Resistant to drought and frost, with higher rooting ability during the cutting propagation.

        High-yielding. The yield of made tea in an area of 201.2 mu in the North-gate of Fuan county (Fujian province) averaged 191.36kg per mu in 1985. Among these, an area of 20.5 mu yielded 303kg made tea per mu.

        According to the analysis conducted by the Tea Research Institute, Chinese Academy of Agricultural Sciences, the contents of caffeine in the one bud and two leaves shoots during spring season averaged 3.83%, amino acids 1.81%, tea polyphenols 28.22%, total catechins 127.06mg/g. The Congou Black Tea prepared with this variety as the raw material has a tight twist leaves with profuse hairs and glossy appearance. Liquor with fragrant aroma as well as brisk and pungent taste.

        It is recommended to cultivate in the land with deep and fertile soil layer, and multiple times of format pruning m the optimum period. To maintain the lateral branches is necessary, so as to increase the branching density.
