Narrowleaf Arnica

Arnica angustifolia subsp. angustifolia

Also Known As - Narrowleaf Leopardbane
Narrowleaf Arnica (Arnica angustifolia subsp. angustifolia) is a flowering, perennial herb native to the forests and meadows of western North America. The species is characterized by rosettes of dark green, narrow, lance-shaped leaves off a sturdy stem reaching eight inches in height. Narrowleaf Arnica has daisy-like blossoms, usually yellow, of just over an inch in diameter that bloom in late summer. As with all species in this family, the leaves and flowers of this plant are not edible but a traditional remedy for inflammation, bruises, and pain. Narrowleaf Arnica can be propagated by division or root cuttings.

watering

Narrowleaf Arnica should be watered regularly, but allowed to dry out slightly between watering. It should be watered approximately once a week during the growing season, which is typically mid-spring through late summer. During colder and dryer times, such as winter, it can be watered about every other week. When watering, you should saturate the soil until you can see moisture coming out of the drainage holes in the container. Let the soil dry out to about an inch or so before watering again. Avoid overwatering as this can cause root rot or other issues.

sunlight

Narrowleaf Arnica (Arnica angustifolia subsp. angustifolia) prefers full sunlight for most of the day. The amount of sunlight should range from 6-7 hours for optimal growth and flowering. Optimum sunlight should be between 10am-4pm for best results. When planting, it is important to make sure the area selected for Narrowleaf Arnica has consistent, direct sunlight. Shade in the afternoon and during the night is beneficial for the plant's growth, health, and flowering; however, too much shade or too much variation in light intensity should be avoided.

pruning

Narrowleaf Arnica typically does not require regular pruning. However, if dead or diseased stems and flowers are present, they can be removed as needed. Additionally, if the plant is becoming overgrown, it can be pinched back in spring before flowering occurs. This will help to promote branching and to keep the plant’s form and flowering in check. When pruning, always remove the stems as close to the ground as possible.
