Propagation of Arnica chamissonis Less. ssp. foliosa (Nutt.) Maguire var. andina (Nutt.) Ediger & Barkl. can be achieved through two methods: seed propagation and vegetative propagation.
Seed propagation
Arnica chamissonis Less. ssp. foliosa (Nutt.) Maguire var. andina (Nutt.) Ediger & Barkl. can be propagated by seed, which is the easiest and most common method. The seeds of Andean arnica are small and lightweight, with a parachute-like structure that helps them to disperse in the wind. For successful propagation, the following steps are recommended:
- Collect mature seed heads in late summer or early fall when the flowers have faded and the seeds have turned brown.
- Place the seed heads in a paper bag and store them in a dry and cool place for several weeks or until the seeds are fully matured.
- Remove the seeds from the seed heads and store them in a labeled container in a cool and dark place until spring.
- In spring, sow the seeds in a seed tray or a nursery bed filled with well-drained soil and cover lightly with soil.
- Water the soil regularly to keep it moist but not waterlogged.
- Transplant the seedlings when they are large enough to handle into individual pots or directly into the garden.
Vegetative propagation
Arnica chamissonis Less. ssp. foliosa (Nutt.) Maguire var. andina (Nutt.) Ediger & Barkl. can also be propagated vegetatively, although it is less common than seed propagation. Vegetative propagation involves taking a part of the plant and growing it into a new plant. The following methods can be used:
- Division: Divide a mature plant in spring or fall into smaller sections, making sure each section has a healthy root system and at least one bud or shoot.
- Cuttings: Take cuttings from a healthy plant in spring or late summer, making sure each cutting has a length of about 4 inches and a few leaves. Dip the cut ends in rooting hormone and plant them in a pot or a nursery bed filled with well-drained soil. Keep them in a warm and humid place until they develop roots and new growth.
Disease and Pest Management for Arnica chamissonis Less. ssp. foliosa (Nutt.) Maguire var. andina (Nutt.) Ediger & Barkl.
