In winter, parts of the ground still sleep quietly, and when the climate gets warmer the next year, they sprout and grow again. As it grows year after year, the underground roots or stems may gradually become hypertrophic or branched. This provides us with a basis for identifying their age; its age can be inferred from the number of branches in its underground part, the size, length and thickness of its stem or root.

Perennial herbs can live for more than two years. The underground parts of some plants are perennial, such as persistent roots or rhizomes, bulbs, tubers and other abnormal organs, while the aboveground parts die every year, and new branches grow from the underground parts in the following spring, such as lotus root, onion, taro, sweet potato, dahlia and so on. In addition, the aboveground and underground parts of some plants are perennial, after flowering and fruiting, the aboveground parts still do not die, and can bear fruit many times, such as evergreen, Ophiopogon japonicus and so on.
