Propagation of Pseudognaphalium luteo-album (L.) Hilliard & B.L.Burtt subsp. luteo-album
Pseudognaphalium luteo-album can be propagated through several methods, including seeds, stem cuttings, and division.
Propagation through Seeds
Seeds of Pseudognaphalium luteo-album can be easily collected from the mature flowerheads. Harvest the flowerheads when they are dry and brown, and the seeds have turned dark. Store the collected seeds in a cool, dry place until planting. Sow the seeds in a well-draining soil mix in spring or early summer. Cover the seeds lightly with soil and provide consistent moisture until the seeds germinate.
Propagation through Stem Cuttings
Propagation through stem cuttings is another method that can be used to propagate Pseudognaphalium luteo-album. Take a 5-7cm long cutting from the plant's stem in spring or early summer. Remove the leaves from the lower part of the cutting and dip the cut end into rooting hormone powder. Plant the cutting in a well-draining soil mix and keep it out of direct sunlight. Provide consistent moisture and wait for the cutting to develop roots and new growth.
Propagation through Division
The plant can also be propagated through division. In late winter or early spring, dig up the plant and carefully divide the root ball into smaller sections with a sharp knife.
