The annual fleabane (Stenactis annuus) belongs to Asteraceae (the Aster family). It is an annual herb that is native to North America. It was introduced into Japan at the beginning of the Meiji period (about 150 years ago). It is naturalized in various places now. It grows from flatlands to the subalpine zone, and its height is 30 to 120 cm. The lower leaves are ovate, with long petioles rough toothed edges. The upper leaves are lanceolate. White flowers bloom from June to October. The ray-flowers are whiter and fewer in number than "Philadelphia fleabane (Erigeron philadelphicus)". The buds will slightly swell. Young shoots are a bit bitter but can be eaten.
