Cuttings of about 5-8 cm can be taken from the plant during the summer months and placed in a rooting hormone before being planted in moist soil. To increase the chances of success, it is recommended to keep the cuttings in a cool and shaded place.
Propagation by division
Propagation by division is suitable for mature plants that have been growing for a few years. The plant can be divided in early spring or fall by carefully separating the clumps of the plant, making sure each division has some roots attached. The new divisions can be planted in a new location, and they will soon establish themselves and start growing.
