More information
July-Oct
Common Name: Burdock
Latin Name: Arctium
minus
Family: Compositae
This a nuisance species common around old barns,
roadsides, and similar places. The leaves are huge. The brown
"cockleburs" are probably the most noticed feature of this Eurasian exotic. They
commonly stick to clothing and shoelaces. The flowers look like green versions of the
brown, round, spiky cockleburs.
June-Aug
Common Name: Plantain
Latin Name: Plantago major
Family: Plantaginaceae
Plantain has small, slender spikes of tight
inconspicuous flowers and seeds. The spikes are only several inches long. The
leaves are all at the base of the plant. The plant is usually not taller than 6-8
inches. Plantain is one of those plants that most people have seen and recognize,
but have never bothered to find out what it was. There are a couple species of
plantain common in the U.P., with nine or ten around the state. Some are native and
some are exotic. One is on the Michigan endangered species list (P. cordata). What we call plantain is not at all related to the tropical
plantain that produces banana-shaped edible fruit.
Aug-Sept
(mature seed)
Common Name: Docks &
Sorrels
Latin Name: Rumex spp.
Family: Polygonaceae
The tall slender, often multi-branched, spikes are
what is usually noticed about the docks. When mature, the chocolate-brown spikes
loaded with seed are readily seen along roadsides and elsewhere. Flowers and leaves
are seldom noticed. The leaves generally grow only at the base of the plant.
The species we tend to see along roadways are exotics from Europe, although there are
several native species of Rumex, some associated with wetlands.
