木芙蓉也称拒霜花(Hibiscus mutabilis),因其花多在10月下旬霜降前后开花而得名。进入深秋,自然界少有其他木本花卉开放,这也是木芙蓉受欢迎的主要原因。但进入11月,江南地区常有强降温天气,遇重霜时花朵不能正常开放,花期会大大缩短。所以若有提早开花的品种,人们就不用担心木芙蓉遇霜而过早地凋谢了。这一愿望已成现实。近年,人们选育出夏季开。 Hibiscus mutabilis, also known as Hibiscus mutabilis, is named for its flowering flowers before and after the fall of the frost in late October. Into the late autumn, there are few other natural woody flowers in nature, which is also the main reason for the popularity of hibiscus. However, in November, Jiangnan region often has strong cooling weather, heavy frost when the flowers can not be normal open, flowering will be greatly reduced. So if you have early flowering varieties, people do not have to worry about the wood Hibiscus frost premature withered. This wish has come true. In recent years, people bred summer.
