'''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 plant|annual]] herb grows to 20-50 cm tall, unbranched or branched only at the base. The [[leaf|leaves]] are trifoliate with a long petiole, each leaflet hairy, 8-16 mm across, with a truncated or bilobed apex. The [[flower]]s 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 [[flower]]s 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===
[[Image:ScarletClover2Web.jpg|thumb|left|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.
