Manchurian chrysanthemum (Dendranthema zawadskii)

Dmitry Poltavsky - Dendranthema zawadskii

Chrysanthemum zawadskii, commonly known as Zawadzki chrysanthemum, is a compact, clump-forming, herbaceous perennial. It is native to a variety of habitats including alpine slopes, streambanks, forest understories, grasslands, and open places from eastern Europe (including in particular the Carpathian and Ural mountains), to Siberia, Japan, Korea, and northern China. Solitary (infrequently appearing in a loose corymb) daisy-like flowers feature white rays and yellow center discs. Flowers bloom in July-September. Genus name comes from the Greek words Chrysos meaning gold and Anthemon meaning flower. Specific epithet was named after Alexander Zawadzki (1798-1868), Polish-Hungarian botanist and naturalist, by Franz Herbich (1791-1865) who discovered this plant growing in the Pieniny Mountains (western Carpathians) in 1829 and subsequently first described it in 1831.
