Hop clover is classified as an annual herbaceous plant that is also a stipulate. The plant is three-leaved and can be found between April and October. The terminal leaflet is distinctly stalked, unlike other clovers. Petioles are usually shorter than the toothed leaflets. The shape of the leaves range from circular to oval. Stems are erect and measure 10 to 30 cm long. The plant has many branched stems with a hairy texture. Hop clover produces 20 to 40 flowers per head and each flower is stalked. The species thrives in temperate regions and does not do as well in dry or hot humid climates.
