Water
Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot. Allow the top inch of soil to dry slightly between waterings for established plants.
Also known as Rydberg's Arnica · Subalpine Leopardbane
Arnica rydbergii, Subalpine Arnica, is a perennial herb with bright yellow, daisy-like flowers, typically found in alpine and subalpine meadows.

Watering, pruning, propagation, and repotting details from plant data
Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot. Allow the top inch of soil to dry slightly between waterings for established plants.
Prune after flowering to remove spent flower stalks. This encourages a tidier appearance and can prevent self-seeding if not desired.
Remove any dead or damaged foliage in late winter or early spring before new growth emerges.
Propagate by division of established clumps in early spring or autumn. Seeds can be sown in autumn or after a period of cold stratification. Germination can be slow and erratic, so patience is required.
Repot container-grown plants every 2-3 years in early spring or autumn. Use a well-draining potting mix, such as a blend of loam, sand, and peat.
Ensure the new pot has adequate drainage holes to prevent water accumulation.
