Propagation of Thesium lynesii Robyns & Lawalrée
Thesium lynesii Robyns & Lawalrée can be propagated by both seeds and stem cuttings. Here is a brief on each of the methods:
Seed Propagation
Thesium lynesii Robyns & Lawalrée can be propagated from seed, which can be collected from the mature plant during late summer or early fall. Once collected, the seed can be dried in an open space, away from direct sunlight, and stored in an airtight container till the next sowing season.
The seeds of Thesium lynesii Robyns & Lawalrée require cold stratification to break the dormancy, which can be achieved by keeping the seeds in a refrigerator for two to three months before sowing them in spring.
The seeds can be sown in a well-draining potting mix and covered with a thin layer of soil. The pot should be kept in a sheltered spot, away from direct sunlight, till the seeds germinate, which usually takes about two to four weeks.
Stem Cuttings
Thesium lynesii Robyns & Lawalrée can be propagated from stem cuttings, which can be taken during the active growth phase of the plant, in spring or early summer.
The stem cuttings should be taken from healthy, disease-free plants and should be about four to six inches long. The cuttings should be dipped in a rooting hormone and planted in a well-draining potting mix. The pot should be kept in a sheltered spot with bright but indirect light until the cuttings have rooted, which usually takes about three to four weeks. Once rooted, the cuttings can be transferred to individual containers or planted directly in the ground.
