White Clover
Trifolium repens L. (Pea family, Fabaceae)


White clover is a cool-season perennial with a prostrate, stoloniferous growth form, 5 to 8 inches long. Leaves and roots develop along the stolon at the nodes. It also develops a taproot.

Leaves: The alternate leaves are composed of 3 leaflets (trifoliate), which may or may not have a “crescent” or “watermark” on the upper surface; membranous stipules lanceolate to ovate, 5/32 to 13/16 inch long; leaf stalk long; leaflets obovate or oval, 3/16 to 13/16 inch long, finely toothed; flowering stalks 2 to 12 inches long.

Flowers: Flowers June to September; the flower heads, each consisting of 40 to 100 flowers, are borne on long stalks from the leaf axils; flowers white but may have a pink hue; flower stalks 2 to 12 inches long; flower heads spherical, 9/16 to 1 inch in diameter; flower stems less than 1/8 inch long, reflexed in age; flowers 3/16 to 3/8 inch long; calyx 1/8 to 3/16 inch long, tube white, teeth green; corolla 1/8 to 3/8 inch long, white, sometimes with pink tinge.

Fruit: The fruit is a legume, less than 3/16 inch long, with 4 to 5 seeds.


White clover adapts only to soil with moderate to good moisture within elevations that generally range from 3,500 to 8,500 feet.


Reproduces by seed and by stoloniferous stems. White clover produces roughly 776,000 seeds per pound.


Native to Europe; white clover rapidly develops a deep fleshy taproot. Mature plants have roots 1 to 1-1/2 inches in diameter and 5 to 8 feet deep. Many large and numerous smaller branches, all well supplied with laterals, spread rather widely and penetrate deeply, furnishing the plant with an excellent absorbing system. White clover may become weedy or invasive in some regions or habitats and may displace desirable vegetation if not properly managed making it a concern in riparian and moist meadow habitats. This species generally occurs as a weed in wildland areas of the Southwestern Region rather than as an invasive plant.
