| Identification | As its name suggests, Burdock Clover has a globose inflorescence a bit like a fruit of burdock (genus Arctium), due to the projecting, acuminate, calyx lobes. | |
| Taxonomic Comments | Trifolium is a large genus of some 240-250 species globally, mostly north-temperate zone. Most are readily recognized as a clover by their 3 broad leaflets and globular to hemispherical head of densely-packed flowers. Flowers vary from white to pink, and red; the hop clovers have tiny yellow flowers. Some species were introduced for their forage value for livestock, others hitched a ride with hay, packing material, etc. Our two native species -- T. carolinianum and T. reflexum -- have suffered great loss of habitat and are now rare. | |
