Breed can be used sow law, cuttage law and Qiegenfa to breed, sow ℃ of 20-25 of gemmiparous comfortable Wen Wei to control, spring, summer, Qiu Jun but, left and right sides of a month after sowing is gemmiparous, sow although the law is OK short time acquires more plant amount, but from the time that sows to blossom longer, still be much commonly so with cuttage breed is given priority to, cuttage with spring, summer two Ji Wei is comfortable period, insert with terminal bud for beautiful, cuttage sends a root extremely easily, cuttage hind can become a young plant about 4 weeks.

繁殖可利用播种法。扦插法及切根法繁殖,播种发芽适温为20-25℃左右,春。夏。秋均可,播种后约1个月左右发芽,播种法虽然可以短时间获得较多的植株数量,但是从播种到开花的时间较长,所以一般还是多以扦插繁殖为主,扦插以春。夏两季为适期,以顶芽插为佳,扦插极轻易发根,扦插后约4周即可成苗。
