Trifolium incarnatum, commonly known as crimson clover or Italian clover, is an herbaceous annual plant native to temperate regions of Europe. It is often found in grasslands, meadows, and fields, where it thrives in well-drained, fertile soils. Crimson clover reaches a height of 8-20 inches and is notable for its trifoliate leaves and vibrant crimson flower spikes that are 1-2 inches long, blooming in late spring to early summer. The flowers are highly attractive to pollinators and add a splash of color to the landscape.

Crimson clover is valued for its ability to fix nitrogen in the soil through a symbiotic relationship with Rhizobia bacteria, making it an excellent cover crop for improving soil fertility. It is also used as forage for livestock due to its high nutritional value and is effective in erosion control. In ornamental settings, it serves as a beautiful ground cover or addition to wildflower meadows. Crimson clover prefers full sun to partial shade and requires moderate watering. While it is generally low-maintenance, it can become weedy and potentially invasive outside its native range, so caution is advised.CC BY-SA 4.0
