Trifolium incarnatum
Trifolium incarnatum, known as crimson clover or Italian clover, is a species of flowering plant in the family Fabaceae, native to most of Europe. It has been introduced to other areas, including the United States and Japan.
This upright annual herb grows to 20–50 cm (8-20") 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.()
