Plant Profile: Trifolium arvense

Trifolium arvense, commonly known as Hare's-foot clover, is a legume that can be either annual or biennial. It is indigenous to Europe and western Asia but is prevalent throughout North Carolina. The name "Hare's-foot" stems from the flower's resemblance to a hare's paw or tail, and it is easily recognized by its fuzzy flower heads. This plant typically thrives in sandy soils found at the edges of fields, along roadways, in sand dunes, and within vineyards and orchards. It is widely distributed across the eastern and Pacific regions of North America.

As a nitrogen-fixing species, Trifolium arvense is often utilized as a cover crop in soils deficient in nitrogen. Its leaves are palatable to sheep and goats, although it is also regarded as an invasive species in certain areas. The plant flourishes in sunny to partially shaded environments, particularly in sandy soils.

In terms of pests and diseases, this plant has a tendency to reseed itself, which can lead to invasiveness in suitable habitats like sandy disturbed areas. Wind can disperse its seeds, enabling rapid germination and the establishment of extensive colonies. The tough seed coating allows the seeds to survive winter and germinate when temperatures become favorable.

However, it is important to note that domestic livestock and horses may experience abdominal blockages if they consume this plant.
