At the end of flowering, when the flowers dry, you can collect the seeds to be placed in the ground immediately, covered with a layer of about half a centimeter of a mix of sand and flower loam.
The seeds, if the weather conditions allow, will germinate in a month, or after the ground thaw.
Where there are large colonies, just look around to find and collect young seedlings, keeping in mind that the proportion must be of a collection every ten identified to not impoverish the population.
Centranthus are also multiplied by division of the tufts, to be performed in spring or by cutting, taking the material to be propagated at the base of the tufts. They are rooted in peat and sand, with the technique of the bag of transparent plastic material to maintain high humidity, and placing them in a bright and warm place.
