White clover (Trifolium repens) is found throughout the temperate regions of the world and is limited only by extreme cold or heat or by drought. In the United States, white clover is found in the eastern half of the country and in the Pacific Northwest.
White clover does best in well-drained silt loam and clay soils of pH 6.0 to 7.0. It does not tolerate saline or highly alkaline soils.
