• Biennial plants live for two years (or two seasons). A biennial plant's vegetative phase occurs in the first season, followed by its reproductive period in the second.
• Perennial plants are those that remain active throughout the year or have a lifespan of more than two growing seasons.
• Flowers are produced by polycarpic plants multiple times during their lives. Polycarpic fruit trees, such as apple and orange trees, blossom every year. Plants are generally either biennial or perennial.
