Propagation of Becium obovatum var. latifolium Sebald
Becium obovatum (E.Mey. ex Benth.) N.E.Br. var. latifolium Sebald, also known as broad-leaved river mint, is a perennial herbaceous plant that belongs to the family Lamiaceae. This plant is native to southern Africa and can be propagated through various methods.
Seed propagation
One way to propagate Becium obovatum var. latifolium Sebald is through seeds. The seeds should be collected when the plant has fully matured and the seed capsules have turned brown. The capsules should be dried for a few days before the seeds are removed and stored in a cool, dry place. To plant the seeds, they can be sown directly into well-prepared soil in spring or autumn, at a depth of about 2mm. The soil should be kept moist but not waterlogged, and the seeds should germinate within 2-4 weeks.
Cuttings propagation
Another method of propagating Becium obovatum var. latifolium Sebald is through cuttings. Softwood cuttings should be taken in spring or early summer when the new growth is still tender. The cuttings should be about 10-15cm long and should be taken from the top of the plant. The leaves on the lower half of the cutting should be removed, and the cutting should be dipped in rooting hormone before it is planted in well-drained potting soil or directly into the garden soil. The cuttings should be watered and kept in a humid environment until roots are established.
Division propagation
Becium obovatum var. latifolium Sebald can also be propagated by dividing established plants. This should be done in spring or autumn when the plant is dormant. The plant should be carefully lifted from the soil, and the roots should be gently separated. Each division should have a healthy root system and should be replanted at the same depth as the original plant. The new plants should be watered and kept moist until they are established.
Overall, Becium obovatum var. latifolium Sebald can be propagated through seeds, cuttings, or division. All three methods can be successful if done correctly, and the resulting plants produce a beautiful addition to any garden or landscape.
