Biology & Spread:
History: Trifolium campestre thrives in temperate regions and does not do as well in dry or hot humid climates. T. campestre is good for pastures because of their nutritional quality and nitrogen fixing abilty. Although this plant is a weedy plant, it is still valuable as a soil builder. T. campestre displays rapid spring growth. Low Hop clover is also known as a food source for some animals and insects although this clover is not eaten as much as it's relative clovers. The plant is usually locally plentiful in the Eastern U.S., but it's value to wildlife is slight.
