Document Summary
In winter, herbaceous plants don"t survive (no woody tissues = no surviving through winter) Complete life cycle in 1 vegetative season (1 year approx) Example: arabidopsis thaliana (small flowering plant native to eurasia,considered a weed) Same thing as annuals but in 2 years ( 2 years to complete life cycle) 1st year is vegetative, 2nd year produces flowers, fruits and then dies. Verbascum thapsus (native to europe, northern africa, and asia, hairy and grows up to 2 meters) Once sexually maturity reached, produces flowers, fruits every year. Trillium grandiflorum (native to eastern north america, commonly known. Note: annual plants produce way more flowers than perennials. Woody plants have woody tissues and last through the winters, always perennial. Example: oak, maple, most large woody trees. Vines with woody tissues (cannot sustain themselves vertically, need a support to cling to) Can complete 1 entire life cycle in 2-3 weeks.
