Alfalfa/Lucerne

The plant superficially resembles clover,especially while young,when trifoliate leaves comprising round leaflets predominate.Later in maturity,leaflets are elongated.It has clusters of small purple flowers followed by fruits spiralled in 2 to 3 turns containing 10–20 seeds. Alfalfa can be sown in spring or fall,and does best on well-drained soils with a neutral pH of 6.8–7.5.Alfalfa requires sustained levels of potassium and phosphorus to grow well.
