Reproduction by seeds. Seeds are useful for two years, after that they decay promptly, since the seeds are very small they can be sown shallow and densely in a seedbed, when seedlings reach 15 cm they can be transplanted to a final spot.
Reproduction by splitting. At the beginning of spring suckers can be split from the plant and sown separately, this method produces less productive plants.
Reproduction by cuttings. In February, 15 cm long cuttings can be cut, remove leaves and plant at an angle 10 cm deep, must be watered and kept damp until roots emerge. At the end of the winter they can be transplanted to a final destiny. Minimum distance for planting is 40 cm between plants and 80 cm between rows.
