China's Flora Tour: An ancient tree that only grows 0.3mm each year

Deep in Yanquan National Forest Park there is a big family of ancient Torreya grandis, among which more than 6,500 trees are over 100 years old. Each year, it only grows 0.3mm in height. The "Torreya grandis King" that stands out with a height of 24 meters is now over 1,500 years old. The luxuriant tree still bears fruit every year,  a miracle of life.

Torreya grandis is a valuable species under second-class state protection in China. It has a long growth period in the plant kingdom. The tree usually blooms in April in the first year and bears fruit in May the second year. It only fully matures in September in the third year. Thus, you can often see flowers and fruit on one tree at the same time.
