Introduced from
America, Erigeron annuus, an annual or biennial, is
one of the most common plants throughout this country, from urban
areas to rural districts, spreading even to subalpine zones. Stems
measure 0.3-1.3m in height with coarse hairs on them and jammed pith
inside. Radical leaves vanish in flowering time. Leaves on the lower
parts are oval, with long pedicles and coarse serrations on the
margins. Leaves on the upper parts are lanceolate; bases taper but
do not embrace the stems. Flower heads are small, about 2cm across,
and bloom on branch tops. Bloom time: June-October. |
