Crimson Clover
Scientific Name: Trifolium incarnatum

Type: winter annual or summer annual legume
Roles: Nutrient source, soil builder, erosion prevention, reseeding inter-row ground cover, livestock, forage

About Crimson Clover:

Crimson clover has a rapid, robust growth for early spring nitrogen for full-season crops. This clover does well in fall growing season as well summer (in cool areas). Because of this clover is a top choice for short-rotation niches as a weed suppressing green manure. Its spectacular beauty when flowering keeps it visible even in a mix with other flowering legumes and is commonly used for roadside vegetation, pastures, erosion control sites, and more!

Crimson clover will winter kill in the northern states most years, but should overwinter in the south.  Deep set roots improve soil tilth and overall soil condition.  Planting clover with a grass or small grain is an excellent cover crop option for erosion and weed control as well as offering the ability to be grazed.

Crimson clover is an introduced winter or summer annual.  The leaves and stems resemble those of red clover. The difference between the two the leaves are round-tipped with more hair on the stems and leaves on crimson clover compared to red clover. Seedlings grow rapidly from the crown forming a rosette. This rosette enlarges as weather becomes favorable. In the spring, the flower stems develop rapidly and end their growth with long, pointed conical flower heads.

Establishment & Fieldwork
In general, plant before or after all danger of frost. Inoculate clover if it hasn’t been grown before. Crimson clover will grow well in about any type of well drained soil, especially sandy loam. It may fare poorly on heavy clay, waterlogged, extremely acid or alkaline soils. Once established, it thrives in cool, moist conditions. Dry soil often hinders fall plantings.
