Which characteristic is true for perennials?

Perennials are indeed characterized by their ability to live for multiple years. Unlike annuals, which complete their life cycle in a single growing season, or biennials, which require two years to complete their life cycle, perennials have the capability to grow, flower, and set seeds over multiple seasons. Furthermore, they can reproduce asexually through rhizomes, tubers, or crowns, allowing them to spread and thrive without the need for replanting each year. This trait of lasting multiple years and having methods of asexual reproduction contributes to the stability and persistence of perennial plant populations in their environments.

Other characteristics mentioned in the options highlight traits associated with annuals or biennials, which do not apply to perennials. Understanding this distinction is crucial for anyone involved in integrated pest management, as the growth habits of plants influence pest populations and management strategies.
