日日春原产非洲东部,广泛栽培于热带和亚热带地区,由于其生性强健,连日开花,花期长达半年,所以又有长春花、日日新、日日草、三万花、四时春等别名。此花传入中国的时间虽已难查考,不过,由宋时著名的金石家洪适曾写的《长春》诗推测,应相当久远,他的诗是这样写的:四季花常发,朝朝得细看;绛英能受暑,绿刺更禁寒。诗文极朴实,意旨却很深邃。 As a result of its strong nature, it blooms for several days and its flowering period lasts for six months. Therefore, there are another species of Catharanthus roseus, Risin New Day, Rizhao Dayan, Thirty Thousand Flowers, and Si Shi Chun Other names. Although it is hard to test the time when this flower was introduced into China, it is quite long ago that the “Changchun” poem written by Hong Shi, a famous stone artist in the Song Dynasty, should have been quite old. His poems are written like this: Look; Jiang Ying British summer, green thorn more cold. Very simple poetry, meaning is very deep.
