Hare's-foot clover
Trifolium arvense
Hare's-foot clover is an annual or biennial herbaceous plant primarily found in dry, sandy habitats. It is characterized by its grey-felted hairy stems and leaves, along with its distinctive elongated inflorescences. The flowers are small and whitish-pink, dominated by long, feathery calyx teeth that give the flower head a fuzzy, fur-like appearance resembling a rabbit's foot.
Details
Habitat function
Important food plant for specialized wild bees and butterfly larvae in open landscapes.
Nutrient uptake
Efficiently absorbs nutrients from barren soils and enriches nitrogen.
Food source for
Nectar source for small bee species; host plant for larvae of the Short-tailed Blue butterfly.
Human use
Traditionally used as a medicinal plant against diarrhea (due to tannins); today often used as an ornament in dried bouquets.
Ecology
Ecological role
Nitrogen fixation through symbiosis with rhizobia; pioneer colonizer of raw soils and sandy fallow lands.
Natural predators
Various phytophagous insects, particularly weevil larvae.
Competitor species
More competitive grasses with increasing eutrophication of the site.
Ecosystem service
Soil improvement through nitrogen input; erosion control on loose sandy soils; pollinator support.
Threats
Agricultural intensification; eutrophication; development of dry habitats; succession due to lack of disturbance.
Scientific profile
Profile
Reproduction
Exclusively generative via seeds; the species is an obligate seed-disperser with high seed production.
Protection & threats
Main threats
Eutrophication via atmospheric nitrogen deposition, succession and scrub encroachment following abandonment of land use, and land sealing.
