Sweet or low-alkaloid varieties have been developed in recent years. These 

 newly developed, nonpoisonous lupines are grown for forage and for soil 

 improvement. 



Borre Blue Lupine 



Borre blue lupine, a sweet type, is adapted to the southern parts of 

 South Carolina, Georgia, and Alabama, as well as the northern part of 

 Florida. It grows well on sandy and more acid soils in these areas. It is 

 used as a soil -improvement crop, furnishes palatable winter grazing, and, 

 in addition, the seed can serve as a high-protein feed supplement. It fits 

 well into a crop rotation with sorghum or sudangrass to provide year around 

 forage. 



Yellow Lupine 



Yellow lupine, which is grown in northern Florida and southern Georgia, 

 is the sweet type and has the same soil preferences as Borre blue lupine. It 

 is equally important for soil improvement and winter grazing. In recent 

 years virus diseases have greatly reduced seed yields. 



MEDICAGO 



The medicagos are winter annual legumes that maintain themselves 

 readily by natural reseeding. The medicagos are not true clovers but, 

 because of their physical resemblance, many species are commonly 

 called clovers. 



Bur-clover 



The bur-clovers are adapted to the cotton-growing areas of the South 

 and to western Washington, Oregon, and California. These legumes prefer 

 moist, well-drained limestone loams. They will, however, make good growth 

 in practically all types of soils, and in California will grow vigorously on 

 poorly drained alkaline soils. 



Bur-clovers are grown as winter cover crops to increase soil fertility 

 and limit erosion. They may also be used for grazing, but they are less 

 palatable than white clover. Sheep raisers do not favor bur -clover on 

 ranges since the burs become entangled in the fleece and reduce the value 

 of the wool. 



Southern bur-clover makes unusual growth during cool weather in all 

 but the coastal areas of those States south of Virginia, Kentucky, and 

 Missouri. Although it maintains itself, Southern bur-clover is a 

 difficult crop to harvest for seed. 



California bur -clover is more susceptible to low temperatures than 

 Southern bur -clover. It provides winter range in those sections of 

 California, Arizona, and Texas having mild winters. 



Button Clover 



Button clover is grown in Tennessee and in northern Alabama and 

 Mississippi. It grows well on well-drained heavy soils and is used for 

 pasture, hay, and soil improvement.
