Annual Perennial

Germination Fast (often 1 to3 days)

Long (sometimes ½ year orlonger)

Growth Fast Slow

Flowering Early andAbundant

At least after one year ofgrowing often much longer

Number of seeds Many Often few

Root system Shallow Extensive

Replanting Every year Long lived



Legumes vs. Non-leguminous plants

Legumes are a specific type of plants that have an association(symbiotic relationship) with bacteria on their roots (root nodules)
