Griscom's Arnica

Arnica griscomii subsp. griscomii

Griscom's Arnica (Arnica griscomii subsp. griscomii) is a perennially flowering plant native to the coniferous forests of the Western United States. It produces beautiful yellow daisy-like flowers atop short stalks in the spring and summer months. The foliage is lance-shaped and holds its shape through the evergreen winters. This hardy species can easily adapt to soil and light conditions, making it an ideal choice for woodlands and garden borders/patios. Its medicinal qualities make it popular for home remedies. When used carefully, it may be applied topically to reduce inflammation or prepare teas to calm headaches and nerves.

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.
