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. |
