Propagation of Gnaphalium niliacum Spreng.
Gnaphalium niliacum Spreng. is a herbaceous perennial plant that is native to South America. It is commonly known as cudweed or rabbit tobacco. The plant produces small, white, and yellow flowers that bloom in the summer. Gnaphalium niliacum Spreng. can be propagated through various methods, including seeds, stem cuttings, and division.

Propagation by Stem Cuttings
Stem cuttings are another method of propagating Gnaphalium niliacum Spreng. Cut a six-inch stem from the plant and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a well-draining soil mix. Keep the soil moist and in a shaded area. The cutting will root in about three to four weeks. Once rooted, move the cutting to its final location.
Propagation by Division
Propagation by division is the simplest method of propagating Gnaphalium niliacum Spreng. It involves dividing the plant into smaller sections and replanting them.
