Explanation:
The perennial plants are the plants that live for more then two years, thous some may argue that they are plants that live more then three years. Whichever the case, they are not short-lived plants, but are capable of surviving for numerous years, unlike the annuals and biennials. Theoretically, the shrubs and trees would fall into this category, but they are classified separately, and this term is not used for them, but for smaller plants that do not have or have very little woody parts. These plants tend to sprout every year, and even though they seemingly die in the autumn, their roots are alive, and they emerge and grow again in the spring, sprouting again. That process repeats itself for numerous years.
