Elytrigia Repens


Regional Noxious. Perennial grass.
Quackgrass has flat, pointed leaves that clasp the stem with claw-like pincers. Its flowers are slender spikes that resemble wheat heads and develop into spikelets arranged in two long rows borne flat side to the stem. Roots are long, slender, white rootstalks with sharp-pointed, yellowish tips.

Quackgrass rapidly invades and reduces the productivity of agricultural crops, rangelands, and pastures. It has sometimes been used to stabilize moist, eroding soils. It is believed to produce chemicals which inhibit the growth of other plants.

In British Columbia, quackgrass grows at low to mid-elevations in fields, gardens, roadsides, and disturbed sites. It is well adapted to moist soils in temperate climates, but is only moderately tolerant of shade.

Quackgrass is common in southern parts of BC and occurs in all agricultural regions. It is considered a threat to the fine seeds industry and forage crops in the Peace River.
