After thousands of years, is there still pollen in wormwood?

After flowering, wormwood usually does not produce pollen after thousands of years. After the Millennium, it is the solar term in autumn, which means that the weather gradually turns cold and plants begin to sleep. The flowering period of wormwood is usually in summer, and with the arrival of autumn, they will gradually stop flowering and withering. Therefore, wormwood will have no new flowers and pollen after thousands of years.
