About Artemisia borealis Pall.
Artemisia borealis Pall. is a perennial cespitose plant that grows 8 to 20 cm tall, occasionally ranging from 6 cm to 40 cm. It is mildly aromatic, grows from a taproot, and has branched caudices. It produces 1 to 5 gray-green, tomentose stems. Its leaves are persistent, along with the plant's basal rosettes, and range in color from gray-green to white. The leaf blades are ovate, measure 2–4 cm long by 0.5–1 cm wide, and are 2–3-pinnately or -ternately lobed. The leaf lobes are linear to narrowly oblong with acute apices, and both leaf surfaces are moderately to densely sericeous. Flower heads are arranged in spiciform, leafy arrays that measure 4–9 cm long by 1–5 cm wide, occasionally ranging up to 12 cm long and as narrow as 0.5 cm wide; proximal heads in the array are sessile, while distal heads are pedunculate. The involucres are hemispheric, and measure 3–4 mm long by 3.5–4 mm wide. The phyllaries are obscurely scarious and densely tomentose-villous. The florets include 8–10 pistillate florets and 15–30 functionally staminate florets; the corollas (or their lobes) are yellow-orange or deep red, and measure 2.2–3.5. The cypselae are oblong-lanceoloid, somewhat compressed, measure 0.4–1 mm (0.016–0.039 in), are faintly nerved, and are glabrous.
