Moss stem is originally a wild plant. Legend has it that Laozi once planted it in the worry-free garden of Taiqing Palace in his hometown. It was not eaten as a vegetable but was used to make elixirs.

Taiqing Palace is only 15 kilometers away from Yimen Town.

During the Ming and Qing Dynasties, when the Taiqing Palace was in war, the seeds of this plant flowed into the public and were obtained by farmers named Zhang in Mengyuan, Yimen. They were processed into tribute dishes 300 years ago and became palace dishes.

However, because this plant has high requirements on water, soil, climate and other conditions, it is difficult to expand its planting in other places.

Dry moss can be harvested twice a year, divided into spring moss and autumn moss. The whole growth period is only about 75 days. It requires soaking buds in wells, cultivating seedlings in borders, and digging ridges for transplanting.

If planted too early, only fiber will be produced but not meat; if planted too late, the weather will get colder and only a handful of moss and dried leaves will fall off.

When harvesting, you need to break the leaves, peel them, use a sharp knife to remove the vegetables, seize the time, and ventilate and dry them.

Moss Gan has enjoyed a high reputation in Hu, Guang and Nanyang areas as early as the Republic of China.

In the golden autumn of October, it is the season for harvesting and processing of dried moss. Businessmen from Nanyang and Huguang came to Yimen Ancient Town with their bags on their backs to buy dried moss.

Nowadays, Taigan has gone abroad and is sold all over the world.
