Spineless Burr Medic Clover - Cavalier

Medicago polymorpha, often referred to as bur clover or burr medic, is a cool season legume predominantly recognized as an annual, though it can occasionally persist as a short-lived perennial in specific areas. Hailing originally from the Mediterranean basin, this plant has managed to colonize various parts of the world especially in milder climates. Typically reaching heights between 6 to 18 inches, it has green leaves and distinctive small yellow flowers with characteristic coiled, bur-like seed pods. These seed pods aid in seed dispersal by attaching to animals, clothing, or fur. Bur clover is rather adaptable showing a preference for well-drained soils and thriving under a spectrum of light conditions from full sun to partial shade. Neutral to slightly alkaline pH levels are ideal though it may tolerate a range of soil pH. Beyond its botanical features, bur clover has earned recognition in agricultural circles for its high protein content making it a valuable grazing resource for livestock. Wildlife, especially certain birds and small mammals, often eat the seeds and the plant provides shelter for a myriad of insects. As a legume, bur medic fixes atmospheric nitrogen thanks to its symbiotic relationship with bacteria residing in its root nodules. 

Cavalier is a spineless burr medic. It has excellent reseeding following fall stands and is a mid-maturing variety flowering in 90 - 95 days. Cavalier grows well in alkaline to slightly acidic soils, above pH 6.0, while still offering good salinity tolerance. It is palatable at all stages of growth with high protein values and excellent nitrogen fixation. Cavalier is not productive in deep sandy soils.
