White clover is the most important pasture legume. It is perennial and grows best in moist, well-drained black loam series of limestone formation. White clover propagates itself by seeds and by its trailing stems. The trailing stems grow roots at each node. These two facts, added to the fact that white clover is a long-lived perennial ensure the plant excellent means for perpetuation. When white clover is seeded in mixtures, from 3 to 6 kg of clover seed are used per hectare. White clover seed is like alsike clover seeds but smaller, and has a pale yellow colour.
White clover should be found in every pasture for three reasons: 1) It is a legume and therefore balances a blue-grass feed. 2) It is a legume, and therefore stores nitrogen in the soil, thus aiding blue-grass in its growth. It grows in midsummer when blue-grass does not do so well.
