- Seed: the method of sowing presupposes the conservation of the seeds for three months in the heat and for another three months in the cold, immersed in damp sand. This stratification will allow the seed to germinate in the spring. Afterwards it will be necessary to insert the seeds in boxes placed in a cold greenhouse.

- Division: reproduction by division must be carried out during the winter, separating the basal shoots with a portion of root and planting them directly at home.
- Grafting: it is possible to graft at the beginning of spring, taking the newly sprouted buds and keeping them in the cold before proceeding with the grafting operation, taking care to seal everything with the appropriate mastic.
