Which type of plants typically live for three years or longer?

Perennials are the type of plants that typically live for three years or longer. They have a life cycle that extends beyond two years, often living for many years, and they bloom and produce flowers each season once they become established. Unlike annuals, which complete their life cycle in a single growing season and then die, or biennials, which take two years to complete their life cycle, perennials return year after year.

Deciduous refers to a type of plant that sheds its leaves seasonally, which is a characteristic of some perennials, but it does not define the plant's lifespan. Therefore, the classification of perennials is more specific in terms of longevity and growth habits, making it the accurate choice in relation to the question.
