Propagation of Thesium sedifolium A.DC. ex Levyns
Thesium sedifolium A.DC. ex Levyns can be propagated through various methods. The following are the most commonly used propagation methods:
Seed Propagation
Seeds of Thesium sedifolium A.DC. ex Levyns can be collected in late summer or early autumn, when the capsules turn brown and start to open. The seeds should be sown immediately after collection as they have a short viability period. The seeds can be sown in a seed tray or directly in the ground. The soil should be moist and well-drained. The seeds should be sown at a depth of 1-2mm and covered lightly with soil. The seedlings will emerge in about two weeks.

Cuttings Propagation
Thesium sedifolium A.DC. ex Levyns can also be propagated by cuttings. Softwood cuttings should be taken in late spring or early summer. The cuttings should be about 10-15cm long and should be taken from the new growth. Remove the leaves from the lower half of the cutting and dip the end in rooting hormone. Place the cutting in a pot with a well-draining soil mix and water regularly. The cutting should be kept in a shaded area until it has developed a good root system, after which it can be moved to a sunny location.
Division Propagation
Division can be done in early spring or late autumn. It involves separating the plant into smaller sections and replanting them. The root ball should be carefully lifted from the ground and the sections should be separated with a sharp knife. Each section should have a good amount of roots and shoots.
