Propagation of Helichrysum Buchananii Engl
Helichrysum buchananii Engl. is a herbaceous perennial plant endemic to the high altitude regions of East Africa. It has attractive yellow flowers and silvery leaves and is often used in traditional medicine and as a herbal tea.
Propagation by Seeds
The most common method of propagating Helichrysum buchananii Engl. is through seeds. The seeds of the plant can be collected from mature dried flowers in the autumn and winter. The collected seeds can be sown directly into the garden beds or pots, or they can be stored and sown later during the spring or summer months. Seeds can be sown in seed trays filled with potting soil, and covered with a very light layer of soil. The seed trays should be kept moist and in a warm location, with a temperature between 18 and 25 degrees Celsius. Seedlings should emerge within two weeks of sowing.
Propagation by Cuttings
Another method of propagation is through cuttings. Cuttings can be taken during the spring or summer months, using softwood material from the upper parts of the stem. Remove the lower leaves from the cuttings, dip the cuttings in rooting hormone, and plant them in pots filled with a moist and well-draining potting mix. Keep the cuttings in a warm and bright location, but away from direct sunlight. Water regularly and cover the pots with a clear plastic bag to maintain humidity. Once roots have formed, the plants can be repotted into larger containers or planted directly into the garden.
Propagation by Division
Division is a third method of propagation of Helichrysum buchananii Engl. Divide the plant during the spring or autumn months when there is active growth. Gently lift and divide the clump into smaller sections, making sure each section has roots and shoots. Plant the divided sections into prepared soil and keep them well-watered until established.
