Convolvulus arvensis L., field bindweed, liseron des champs
Prostrate or climbing perennial with a deep and extensive root
system; allogamous; stems often more than 10 feet (30 dm.) long;
stems often twine around other plants; flowers from white to
pink; throughout our range, with the possible exception of
Prince Edward Island and Newfoundland; cultivated land, grain
fields, meadows, waste places, and roadsides; introduced from
Europe.
Cuscuta campestris Yunck., field dodder, cuscute des champs
Annual plant, lacking chlorophyll, that is parasitic on other
plants; stems are orange or reddish; small white or cream-coloured
flowers are single or in clusters; various parasitic dodders are
present throughout our area; native to North America. Seeds
germinate in the soil and produce slender stems that lack
chlorophyll. Unless the stem encounters a host plant within a
short period, it withers and dies. If the young stem soon comes
in contract with a living plant, it twines around it and
develops suckers that penetrate the plant. Food is received
through these suckers and the dodder loses all contact with the
soil.
