Propagation of Arnica lonchophylla Greene ssp. chionopappa (Fern.) Maguire
The Arnica lonchophylla Greene ssp. chionopappa (Fern.) Maguire commonly known as pale mountain arnica is propagated by several techniques. The most common methods include:
1. Seed propagation:
The pale mountain arnica is propagated by seeds which are harvested from mature flowers in late summer or early autumn. The seeds should be dried and cleaned before sowing. The seeds can then be sown in well-draining soil in a sunny spot. Seedlings should appear after two to four weeks of sowing.
2. Division:
This plant can also be propagated by division. This method involves dividing the root clump into smaller pieces and replanting them in well-drained soil in a sunny location. The best time to divide the plant is in early spring when new growth appears.
3. Cuttings:
The pale mountain arnica can also be propagated by stem cuttings. Cuttings are taken from the stem tips in spring or early summer. The cuttings should be about 4-5 inches long and should have a couple of leaves. The cuttings are then planted in well-draining soil and placed in a location with partial shade. Roots should form within a few weeks, and new growth should appear in a couple of months.
