Its seeds have a period of dormancy, if it is directly to its seedlings, it needs to wait for more than a year, it will slowly grow seedlings, so to successfully raise seedlings, it is necessary to first treat the seeds, in order to break its dormancy period.
First put its seeds in the water for 1 to 2 days, then pull them out, add some wet sand, then hold the wet sand into a group, until there is no water leaching. After that, put it in a container and water it to keep it moist. This treatment method is mostly used in winter, and then in spring, it can be taken out for drying. When the seeds are half cracked, they can be planted in the flower soil.
In terms of production, the most commonly used method is to use the current year's flower branches for cutting seedling, which will make it easier to survive. Cut off its twigs and insert them into the soil to wait for rooting.
If some of the more valuable varieties, it is very difficult to cut, at this time we can use the method of layering or grafting to cultivate seedlings for it, so that flowers can be produced in that year.
If it is used as a potted seedling, it is necessary to select some good old branches, and then use the method of layering to raise seedlings for it. If it is used as cut flower seedlings, it is necessary to choose the colorful varieties that can form flower picking branches to raise seedlings, so as to make it more beautiful.
