Global Range: Regional endemic of Asiatic coast of NW Pacific, from Japan and Korea along Russian coast to outermost Aleutians (Alaska, USA). Ohwi (Flora of Japan, 1965) gives range as "Hokkaido, Honshu (n. Kanto Distr. and northw.) -- Korea, Sakhalin, Kuriles, Kamchatka, and Ochotsk Sea region; natualized in Europe and North America." Hulten (1968) records for easternmost Aleutians, Alaska.

Far East (Amgunskiy and Ussuriyskiy regions, Kamchatka, Sakhalin, southern Kuril Islands), Scandinavia, Japan and North America (Alaska). Along streams, near the sea shore on gravelly soil, on slopes.

Perennials, (15–)20–60(–70) cm (mat-forming), sometimes faintly aromatic (rhizomes creeping, relatively thin). Stems 1–3, erect or ascending, white, simple (stout), densely tomentose to floccose. Leaves basal and cauline (petiolate), silver-gray; blades oblanceolate, (proximalmost) 3–10 × 1–5 cm, pinnatifid (lobes relatively broad, rounded; distal leaves, on flowering stems, smaller), faces densely tomentose. Heads (erect or spreading, peduncles 0 or to 3 mm) in dense, paniculiform, racemiform, or spiciform arrays 8–20 × 2–4 cm. Involucres broadly campanulate, 5–8 × 6–7 mm. Phyllaries broadly lanceolate, tomentose. Florets: pistillate 12–16; bisexual 25–30; corollas yellow (narrow or tubular), 3.2–4 mm (unusually large), glabrous or sparsely hairy (style branches prominent, erect, blunt). Cypselae (dark brown) narrowly oblong-linear (slightly flattened, smooth), 3–4 mm, glabrous. 2n = 18.

Creeping perennial. Sterile stems numerous, 20-30 cm. Flowering shoots solitary, rarely 2 or 3, thickened, up to 50 cm. Leaves petiolate, spathulate or ovate, deeply toothed. Entire plant silver-white tomentose. Flower heads stalked, cup-shaped, 5-8 mm long in spike-like inflorescence. V - early spring to late autumn. Fl - August. Fr - October (not every year). P - by seed or cuttings and also by division. Does well in sunny position and on well-drained soil. Z 5 (4).

Comments: Sand dunes along the seacoast (Japan).

Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Estimated Number of Occurrences: 81 to >300

Comments: As a native plant, has substantial but not large range along NW coast of Pacific, from Japan and Korea along the Russian coast to the outermost Aleutian islands (Alaska, USA). Also establised as an escape from cultivation in eastern North America, Europe, and Hawaii.

Canada

Rounded National Status Rank: NNA - Not Applicable

United States

Rounded National Status Rank: N1 - Critically Imperiled

Rounded Global Status Rank: G4 - Apparently Secure

Reasons: Substantial but not large native range; plant is stoloniferous, and able to colonize large areas of open sand. Only native range is considered here; species is also established as an exotic in eastern North America, Hawaii, and Europe.

Global Short Term Trend: Unknown

Comments: Native habitat subject to some disturbance and development, although northward of the most populated areas; as an exotic, becoming locally abundant in areas of eastern North America.
