Herbaceous plants are divided into groups, as perennials, biennials, 

 annuals and bulbs. Perennials are plants whose tops die back, but 

 whose roots live on from year to year, producing new tops each season. 

 Biennials lose their tops but require two years to complete their life 

 cycle and bear flowers. When reproduction is complete the plant dies. 

 Annuals complete their life cycle in one year and die. Bulbs are 

 flashy roots or buds which are perennial, but in most cases must be 

 taken up and stored over winter. There are three types of "bulbs".
