"Apoi-azuma-giku" (Erigeron thunbergii var. angustifolius) belongs to Asteraceae (the Aster family). It is a perennial herb that is endemic to Mount Apoi, northwest of Cape Erimo in Hokkaido, Japan. It grows in sandy gravel and grassland in peridotite areas, and is 10-15 cm tall. It is a variant of the "Miyama-azuma-giku", but its basal leaves are narrower and less hairy. From May to July, dark-purple flower stalks extend, producing flower-heads with white ray flowers. Some flowers are tinged reddish-purple in color.
