Propagation of Syncolostemon lanceolatus Gürke var. cooperi (Briq.) N.E.Br.
Syncolostemon lanceolatus Gürke var. cooperi (Briq.) N.E.Br. can be propagated through various methods, including:
Seed propagation
The most common method of propagating Syncolostemon lanceolatus Gürke var. cooperi (Briq.) N.E.Br. is through seed propagation. The seeds of the plant can be collected and sown in a suitable soil mixture, such as one containing peat, sand, and perlite.
The seeds should be sown thinly on the soil surface and then covered with a thin layer of soil. The soil should be kept moist, but not too wet, and the container should be placed in a warm, well-lit area. Germination can be expected within a few weeks, and once the seedlings have developed enough, they can be transplanted into individual pots.
Cuttings propagation
Another method of propagating Syncolostemon lanceolatus Gürke var. cooperi (Briq.) N.E.Br. is through stem cuttings. Cuttings of healthy, mature stems can be taken and planted in a suitable soil mixture, such as one containing a mix of peat, sand, and perlite.
The cuttings should be around 5-10cm in length and should be taken from the plant in spring or summer. The leaves should be stripped from the lower half of the stem, and the cuttings should be planted in the soil mixture, making sure the soil is kept moist. The container should be placed in a warm, well-lit area, and once the new growth has developed, the plant can be transplanted into individual pots.
