Solidago multiradiata

Solidago multiradiata, the Rocky Mountain or northern goldenrod, is a perennial herbaceous plant in the Asteraceae native to arctic and subalpine North America from Alaska and the Yukon south through the western mountains to California, New Mexico, and the Great Lakes region. Plants arise from a short, branching caudex and produce one to several erect, simple stems 5 to 50 centimetres tall, often reddish and sparsely hairy. The alternate basal leaves are spatulate to oblanceolate, 2 to 12 centimetres long, with ciliate margins and three prominent veins; stem leaves are smaller and sessile. The inflorescence is a compact, flat-topped to short cylindrical corymb of small yellow heads, each with 13 or more ray florets surrounding 13 to 35 disc florets, distinguishing the species from most other goldenrods by its dense, few-headed cluster. The fruit is a small pubescent achene with a white pappus.
