This perenial herb is also known as birdfoot trefoil, bloomfell, cat's
clover, crowtoes, and ground honeysuckle. Its leaves are finestemmed and
composed of 5 linear leaflets. In many places of the Northern US this
plant forms dense stands. Its easily identified from a distance because
of the many clustered faboid-like yellow flowers.
This plant was introduced from Europe and is now used in the US as an
agricultural crop. It is one of the few legumes that does not cause bloat
in cattle. Because of this is is increasingly important as a pasture and
a hay crop.
It is considered a weedy species in some localities however. It has a
deep rootstock and comes back year after year. It tolerates both wet and
dry conditions due to this deep root base.
