Grass species can be difficult to
identify, but there are certain grasses we commonly see but don't know the names of.
Often, it is the seed head that has distinctive characteristics. The
following are some of the common sights along our roadsides.

Summer
Common Name: Timothy Grass
Latin Name: Phleum
pratense
Family: Gramineae
Timothy grass is one of our most common grasses.
It's tight, cigar-shaped flower heads are easy to spot. They are similar to
the foxtails (Setaria spp.), but appear with shorter "hairs".
The heads are 1-2 inches long. According to Voss, we do have a native Phleum in the U.P., but it only occurs on the Keweenaw peninsula.
However, the DNR lists it as no longer growing in the state.
Summer
Common Name: Reed Canary Grass
Latin Name: Phalaris arundinacea
Family: Gramineae
Reed canary grass forms thick colonies of grass with blades about a
1/2-inch wide. It prefers soils that retain some moisture during most of the growing
season and is more common in marshes and along ditches. In general appearance, the
seed head is dense, rough-looking, and somewhat flattened. The grassy part usually
stands 1-2 tall.
Summer
Common Name: Red Top
Latin Name: Festuca rubra
Family: Gramineae
Red top is one of the several fescues which are
sold for lawn seed. As the name suggests, the loosely arranged, delicate-looking
seed head is reddish-brown in color. Individual seeds are easy to see. Grass
blades slender. Plants stand 2-3 feet tall.
Summer
Common Name: Smooth
Brome
Latin Name: Bromus inermis
Family: Gramineae
Like red top,
smooth brome also has a spreading, delicate-looking seed head. However, the seeds of
smooth brome are longer, maybe a half-inch. They look a bit like beech buds (if that
helps). Blades are 1/4 to 1/2 inch wide.
Summer
Common Name: Beach
Grass
Latin Name: Ammophila
breviligulata
Family: Gramineae
Beach grass is most commonly found in very sandy places such as beaches,
dunes, and right-of-ways. Where roads pass through sandy outwash plains, beach grass
can sometimes be found. It grows in clumps up to 2-3 feet tall. The
flower spikes are rough-looking and about 10-15 inches long.
