Propagation methods of Wollastonia Biflora
Wollastonia biflora (L.) DC., commonly known as the Goldenrod tree or Two-flowered Wollastonia, is a shrub native to the Americas, specifically found in Colombia, Mexico, and the United States. The plant can reach up to 3 meters in height and has a broad range of applications both medicinal and cosmetic
Seeds
The primary method of propagating Wollastonia biflora is through seeds. The plant naturally spreads by self-seeding. The seeds need to be collected just as they start to ripen from the flower heads. After collection, remove them from the plant and let them dry for two to three days.
Sow the seeds into a container filled with sterilized soil. It should be moist but not waterlogged. Lightly press the seeds into the soil and cover them with a thin layer of soil. Germination can take more than two weeks.
Cuttings
Propagating from cuttings is also a possible method to produce Wollastonia biflora. Take cuttings from the plant's stems that are actively growing and about 15-20cm in length. The stem should be removed with a clean, sharp knife and immediately placed in moist, sterilized soil or a water-filled container.
Water the cutting just enough to keep the soil medium or water fresh without causing saturation. Overwatering will cause the cutting to rot. The cutting will form roots within two months and will be ready for transplanting.
Air Layering
Air layering involves wounding a stem, packing the wound with soil or moss, and then wrapping it with plastic to encourage the formation of roots. This method is useful when the plant has woody stems too thick for cuttings.
It's essential to choose a healthy stem with no damage or diseases. Choose a spot on the stem around 10-15cm away from the top where there is no leaves. Gently wound the bark to a width of around 2mm and dust it with rooting hormone. Wrap the wound with moss and plastic wrap.
After a few weeks, roots should have formed. Cut the stem below the new roots and pot it in a container filled with sterilized soil.
Conclusion
Wollastonia biflora is a versatile plant with broad range of medicinal and cosmetic applications. Propagating it from seeds, cuttings or air layering can be achieved quite easily when the recommended procedures are followed.
