Propagation of Helichrysum pachyrrhizum Harv.
Helichrysum pachyrrhizum Harv., also known as the ivory everlasting, is a small shrub with silver-grey leaves and white or pale yellow flowers. It is endemic to the western and southern coastal regions of South Africa and is widely cultivated as an ornamental plant. The following are the different methods of propagating H. pachyrrhizum:
Seed Propagation
The most common method of propagating H. pachyrrhizum is through seeds. Sow the seeds in spring or early summer in shallow trays or pots filled with a well-draining soil mix. Cover the seeds lightly with soil, and water gently. Place the trays in a warm, brightly lit area, but protect them from direct sunlight. The seeds will germinate in around two to four weeks.
Cuttings Propagation
Cuttings is another method of propagating H. pachyrrhizum. Take semi-ripe cuttings in late summer or early autumn, when the plant has finished flowering. Cuttings around 8 to 10 cm long should be taken from the current year's growth and treated with rooting hormone. They are then inserted into pots or trays filled with a well-draining soil mix. Cover the pots with a plastic bag to maintain humidity and keep them in a bright, warm location. The cuttings will root in about 3-4 weeks.
Division Propagation
Division is a less common method of propagating H. pachyrrhizum. It works well for older or established plants. Dig up the plant carefully, and separate the clumps into smaller sections, each with roots and shoots. Replant the divided sections into pots or a new bed filled with a well-draining soil mix. Keep the soil moist, and shade them from the sun until new growth appears.
