Stellate Edelweiss – Leontopodium stellatum Khokhr. – is the endemic species distributed locally at the coast of Tauysk Inlet (the northern coast of the Sea of Okhotsk). The natural habitat of the species is only 1.5–2 km2. The description of plant communities and their microclimate conditions are given. Edelweiss is mesoxerophyte, growing on the steep seaside slopes of S, SW expositions in the forb and grass-forb meadows which alternate with rocks and stones. The information concerning biomorphology, age status, ontogenetic spectrum and phenology is also given. It is shown that Edelweiss has high seed production, and seeds keep viability more than 90 % during 3.5 years. It is recommended to include L. stellatum in the Regional Red Data List as vulnerable, endemic plant of the northern coast of the Sea of Okhotsk. The habitats of the plant need special protection.
