The Atlantica subspecies also known as Bolós, grows only in the extended areas from the south-west of France to southern Portugal. It is overall very rare and even decreasing in number due to increasing agriculture and human habitat. Apuseni Mountain areas have Arnica Montana habitats which are organic certified
Soil
Arnica Montana can grow on a wide variety of soils. It can tolerate fine, coarse to medium type of soil. It is usually found on sloppy surface land, on medium acidic or alkaline rock, bad landscape on the mountain ranges, which is usually with bedrock on the outer part, on acidic soil that is well drained and on soil with poor nutrients. It grows well in a combination of humus oriented and dry peat, loam and sand. It should have a pH level of 5 to 6 which can be increased. It does not prefer limy soil. It usually prefers fewer nutrients. The commercially available all purpose fertilizer can provide all nutrients to Arnica Montana.
Planting
Arnica is a flowering herbaceous plant that is hardy to all temperate zones. It is best grown at high elevations. Arnica Montana makes sturdy clumps in the native habitat and so it should be planted in a moist and damp soil. There should be a gap of about 2 feet between the plants to provide the required space. The best method to grow the plant is by using the standard flower seed planting method. In this method, the seeds are sown in a spongy soil in pots and kept evenly damp and moist during the period of germination. The germination process takes place in about a couple of weeks. After the germination, the plant can be transplanted.
Watering
Regular watering is required for this plant. In normal climate, pour around 1.5 liters of water every 2 to 3 weeks. In hot and dry climate, the frequency should be increased to 1 to 2 weeks and even more often if it is extremely hot climate. The growing substratum of Arnica Montana should be always kept wet and moist. Care should be taken to prevent over watering and water stagnation.
Temperature and Humidity
Arnica Montana enjoys full to partial sun. Although they tend to bloom in full sun, it can also grow in partial shade as well. It also helps to protect the plant from the elements in the warmer climate. It is less than ideal to grow in coastal areas where there is humidity. If Arnica is grown as a container plant, then it should be placed near a north facing window to get moderate sun exposure
