Annual plants have a lifespan of only one year. They germinate, grow, flower and die within a year.
Biennial plants have a lifespan of two years. They germinate, grow, flower and die within the course of two years.
Monocarpic plants are the plants that flower only once in their entire lifetime. After flowering, they produce fruits and then they die. Wheat and rice are annual, monocarpic plants. Carrot and radish are biennial, monocarpic plants.
Bamboo has a long life span of approximately 40-80 years (not a biennial plant) but it flowers only once in a lifetime (monocarpic plant). They stay without flowering for the longest amount of time and die immediately after flowering.
