White Clover

Trifolium repens L.
White clover is widely distributed, especially in cool temperate climates. The plant has stolons or creeping stems near the soil surface. Leaves, flowers, and roots grow directly from these stolons. It is a relatively short plant with indeterminate growth, although taller types can grow up to 25 cm (10 in).The common or white Dutch is small and low growing, while the large type (e.g., Ladino) can be four times larger than the common type. Intermediate types have characteristics that are a mix of the two forms, and are commonly used for pasture.
There are 3 leaflets attached at a single point, and are dark green, often with a white watermark. Leaflets are finely toothed, hairless, and nearly round, up to 3 cm (1 1/4 in.) wide.
Seedling plants develop a taproot, but older plants have threadlike, fibrous roots growing from detached stolons. White clover has one of the lowest root-to-shoot ratios of the legumes. Flower heads can have up to 100 flowers, which are cross-pollinated. Seed pods develop hard, yellow to red seeds.
