Arnica parryi
Also called Rayless arnica, Parry arnica, Nodding Arnica, Sonne's Arnica
Parry's arnica is a North American perennial wildflower of mountain forests and alpine meadows, grown mainly in cool gardens rather than as a houseplant. Its key to success is cool, moist-but-drained conditions and full sun or light shade, with the plant sometimes listed in the sources as Arnica parryi in the daisy family.
Arnica parryi is a North American species of flowering plant known by the common names Parry's arnica or nodding arnica. It is native to western Canada (Yukon, British Columbia, Alberta) and the western United States as far south as Inyo County, California and McKinley County, New Mexico. It grows in temperate coniferous forests and alpine meadows in mountainous areas, primarily the Rocky Mountains, Cascades, and Sierra Nevada.
Arnica parryi is a rhizomatous perennial herb producing a single unbranched stem to heights between 10 and 60 centimeters. There are oval-shaped leaves around the base of the stem and a few pairs of longer, narrower petioled leaves above them. The leaves may approach 20 centimeters in length on larger individuals. The petioles, leaves, and flower stems and bracts are sparsely to densely coated with short white hairs.
