Short Description

Hare's-foot clover can grow to a height of 40 cm.

The leaves grow alternately on the stem. They are divided into three leaflets (trifoliate). The three individual leaflets are lance-shaped to oval.

The stem is upright and frequently highly branched. It is covered in fine woolly hairs.

The small flowers are densely clustered in globular flower heads. The colour is due to the long, shaggily haired reddish sepals. Each individual floret has only a single mirror axis (mirror-symmetric). The flower consists of five white petals. The large upper petal protrudes upwards. The two lower petals form a hollow boat that surrounds the anthers and pistil.

he fruit is a capsule containing one or two seeds.

In the city

Hare's-foot clover can frequently be found in towns in nutrient-poor grassland or wasteland. It prefers dry, sunny sites on nutrient-poor sandy soil. Most soils influenced by humans tend to have a high nutrient content and thus are unsuitable for this plant. For that reason, hare’s-foot clover is becoming increasingly rare in towns.

Fun Facts

  • It is an indicator plant for drought and nutrient-poor sites.

  • Symbiosis with root-nodulation bacteria is typical for members of the papilionaceae family. The bacteria supply the plant with nitrogen. As the bacteria require a plant to fix nitrogen, this biological interaction is beneficial to both species (symbiosis).

  • A papilionaceous flower is a form of flower typical for most members of the legume family.

  • It flowers from June to July.

  • Endangerment level Germany: not endangered
