Why don't cotton flowers need low temperature vernalization?

In line with the four seasons exchange. Some plants want to bloom in early spring for various reasons, and have developed a mechanism called vernalization, which is set to bloom only after a period of low temperature, that is, after winter. If it is high temperature vernalization, it may be because of some high temperature weather, and then it will bloom, and then it may bloom in spring, summer and autumn, and then it is not a plant that blooms in spring, so there will be no vernalization.
