There are also early blooming varieties that bloom 50 to 70 days after sowing, so they should be divided into early blooming and autumn blooming to sow seeds.

2. Cutting: cutting propagation is carried out in May. A sturdy top branch can be selected, a section 8 cm to 10 cm long can be cut as cuttings, 3 to 5 plants as a clump in a flowerpot, the pot should be buried in the soil, 4 cm to 5 cm exposed to the ground, watering shade, and rooting half a month later.
