Crepis tectorum
Also called Narrow Leaved Hawk's Beard, Narrow Leaved Hawksbeard, Annual Hawksbeard, Narrow Leaf Hawk's Beard, Rooftop Hawksbeard, Narrow Leaved Hawk’s Beard
Narrowleaf hawksbeard is an annual or winter annual weed in the daisy family, usually 30 to 100 cm tall, with yellow dandelion-like flowers. It is a weed of disturbed ground, roadsides and fields rather than a garden plant, and is invasive in North America.
Crepis tectorum, commonly referred to as the narrowleaf hawksbeard or narrow-leaved hawk's-beard, is an annual or winter annual plant between 30 and 100 centimetres in height. Originating in Siberia before being introduced to Canada in 1890, the narrowleaf hawksbeard is an invasive species. It has one branched, hairless and leafy stem during maturity, and yellow leaves which are less than 0.5 inches (13 mm) wide and arranged in an alternate manner.
The narrowleaf hawksbeard's scientific name 'Crepis tectorum' originates from the Greek word krepis meaning sandal or slipper, which refers to the shape of the seed.
Crepis tectorum is native to most of Europe, as well as northern and central Asia (Russia, Kazakhstan, Mongolia, and parts of China (Inner Mongolia, Heilongjiang, Xinjiang)).
