This species is easily spotted near mountain streams and in meadows, especially at higher altitudes. Mountain Arnica is drought tolerant but prefers cool, moist climates. It makes an attractive addition to rock gardens, and is a popular choice for those looking for an easy to grow, low-maintenance flower.

watering

Griscom's Arnica should be watered once every 2 to 3 weeks during the spring and summer months; during the fall and winter months, water should be reduced to once a month. The soil should always be kept lightly moist, not overly damp or dry. When watering, do so at the base of the plant, so as to not get the foliage wet. Watering with a watering can, or a soaker hose, helps to keep the foliage dry.

sunlight

Griscom's Arnica (Arnica griscomii subsp. griscomii) does best with full sun during the warmer months of the year, particularly in the early morning and late afternoon hours. During the cooler months, a partial sun location is ideal for this plant species. In general, it is best to provide at least 6 hours of direct sunlight per day.

pruning

Griscom's Arnica (Arnica griscomii subsp. griscomii) should be pruned once a year in late winter, preferably before new growth begins in the spring. When pruning, remove dead, damaged, and crossing stems and leave healthy stems with plenty of room between them. Prune lightly, as the plant is shallow-rooted and too much pruning can damage it. Additionally, removing a few older stems from the center of the plant can help promote new growth and should be done periodically.
