Photos and Pictures
Broad-leaved plantain. A Plant.
B. Seedling, side view. C. Younger seedling.
Stems & Roots: Root system thick
Leaves: Leaves all in a basal rosette,
oval or elliptic, 5-30cm (2-12in.) long, the blade about as long
as its thick green stalk, smooth or somewhat rough-hairy, with 3
to several prominent veins radiating from the leafstalk towards
the tip, margins smooth or irregularly toothed.
Flowers & Fruit: Flowers in compact
spikes on erect, leafless stalks from among the basal leaves; each
spike about the size and shape of a lead pencil but consisting of
many, tiny, stalkless, greenish flowers giving it a coarsely granular
texture; each flower about 2-3mm (1/12-1/8in.) across, with 4 sepals,
4 petals, 2 stamens and 1 pistil; the egg-shaped seedpod developing
beneath the withering flower; this mature seedpod splitting apart
with a circular fracture around its middle so that the top part
drops off and releases the 5 to 16 dark brown or nearly black angular
seeds, each about 1mm (1/25in.) long. Flowers and sets seed from
spring until late autumn.
Habitat: Broad-leaved plantain is
very common in all but the most remote unsettled areas of Ontario
occurring in cultivated land, pastures, meadows, waste places, roadsides,
lawns and gardens.
Similar Species: It is distinguished by
its rosette of dull green, oval leaves with thick green stalks,
and its elongated spikes of tiny green flowers each followed by
a small egg-shaped pod with usually more than 5 tiny dark brown
or nearly black seeds.
