Propagation of Gnaphalium pilosellum L.f.
Gnaphalium pilosellum L.f., commonly known as yellow cudweed, is a herbaceous plant from the Asteraceae family. It is native to Europe but has naturalized in other parts of the world due to its ornamental value. Propagation of Gnaphalium pilosellum is relatively easy, and the plant can be propagated through seeds, cuttings, and division.
Propagation by Seeds
Gnaphalium pilosellum produces small, black, spindle-shaped seeds that can be collected from the dried flower heads. Sow the seeds in late winter or early spring, in a well-draining potting mixture. Cover the seeds thinly with soil and keep them moist. Germination usually occurs within 2-3 weeks, and seedlings can be transplanted into individual pots when they are big enough to handle.

Gnaphalium pilosellum can be propagated through stem cuttings taken from the parent plant. Take 10-15 cm long stem cuttings from mature plants during the growing season. Remove the lower leaves and dip the cut end in rooting hormone. Insert the cuttings into a well-draining potting mix and keep them moist. After a few weeks, the cuttings will develop roots, and new growth will appear.
Propagation by Division
Gnaphalium pilosellum can also be propagated through division. This method is best done in early spring or late autumn, when the plant is dormant. Dig up the parent plant and gently separate the roots into small clumps. Replant the clumps into individual pots or in the ground, making sure the soil is well-draining and moist.
Propagation of Gnaphalium pilosellum is easy and straightforward. Propagating new plants from seeds, cuttings, or division is an excellent way to expand your collection of this beautiful plant.
Disease and Pest Management for Gnaphalium pilosellum L.f.
Gnaphalium pilosellum L.f., commonly called rabbit-tobacco or everlasting cudweed, is a plant species that belongs to the family Asteraceae.
