(Redirected from Trifolium incarnatum)
'Crimson clover' (''Trifolium incarnatum''), also known as 'Italian clover', is a species of
clover in the family
Fabaceae, native to most of
Europe. The species name ''incarnatum'' means "blood red".
This upright
annual herb grows to 20-50 cm tall, unbranched or branched only at the base. The
leaves are trifoliate with a long petiole, each leaflet hairy, 8-16 mm across, with a truncated or bilobed apex. The
flowers are produced throughout the spring and summer, rich red or crimson, congested on an elongated spike
inflorescence 3-5 cm tall and 1.5 cm broad; the individual
flowers are up to 10-13 mm long and have five petals. The banner of each flower does not sit upright, but folds forward.
Cultivation and uses

Crimson clover growing in Texas.
Crimson clover is widely grown as a
protein-rich
forage crop for
cattle and other
livestock. It can typically be found in forest margins, fields and roadsides.
It is sown as quickly as possible after the removal of a grain crop at the rate of 20-22 kg/ha. It is found to succeed better when only the surface of the soil is stirred by the scarifier and harrow than when a ploughing is given. It grows rapidly in spring, and yields an abundant crop of green food, peculiarly palatable to live stock. It is also suitable for making into hay. Only one cutting, however, can be obtained, as it does not shoot again after being mown.
In
Great Britain it is most valuable in the south, less successful in northern regions.
It has been introduced into the
United States, originally as forage for cattle. It is often used for roadside
erosion control, as well as beautification, even though it tends to eliminate all other desirable spring and early-summer species of native vegetation in the area which it is planted.
