Clustered clover

Trifolium glomeratum, the clustered clover, is an annual herb in the family Fabaceae native to the Mediterranean region, including southern Europe, North Africa, and southwestern Asia. Like other clovers, it has trifoliate leaves and produces small, globe-shaped flower heads composed of numerous tiny pink to purplish-pink pea-type flowers. The specific epithet glomeratum means 'clustered into a rounded mass,' referring to the tightly grouped flowerheads that remain sessile (stalkless) amid the upper leaves. The species grows in dry, disturbed ground, sandy fields, roadsides, grasslands, and coastal areas where soils are thin and nutrient-poor. T. glomeratum has been widely naturalized outside its native range, particularly in Australia, New Zealand, South Africa, and parts of North and South America, where it can become a common weed of agricultural margins and waste ground. Like all clovers, it fixes atmospheric nitrogen through root nodule bacteria, contributing to soil fertility. It has not been formally evaluated by the IUCN for conservation status. The species is palatable to livestock and may be grazed where abundant.
