IIntroduced
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 their surface and a 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. |
