White clover is a perennial clover most suited to higher rainfall areas of 700mm+ rainfall or under irrigation. It is usually an important component of a mix with ryegrass for dairy farmers boosting milk production. White clover can grow over a wide range of soil types and will tolerate water logging. In more recent times there are some new cultivars which have been bred to persist in lower rainfall sheep grazing areas of approximately 600mm rainfall. These types have small dense leaves with high stolon density and a vigorous root system, enabling them to tolerate heavy grazing. There have been some new large leaved cultivars released on the market also showing higher production but still not as persistent as the smaller prostrate cultivars. Generally speaking the larger the leaf the more rainfall and strict grazing management is required for them to persist. The following cultivars are grouped according to their leaf size and annual rainfall requirement.
