Which of the following best describes a simple perennial plant?

A simple perennial plant is accurately described by the definition of a plant that lives for multiple years and produces seeds. Unlike annual plants that complete their life cycle in one season, or biennials that take two years to complete their growth cycle, perennials persist for many growing seasons. They often go through cycles of dormancy and growth, but their root systems remain alive year after year. This ability to survive and regrow allows them to produce seeds over multiple seasons, distinguishing them from shorter-lived plant varieties.

The other descriptions do not fit the definition of a simple perennial. Annual plants are characterized by living for just one growing season, and trees, while sometimes perennial, do not specifically apply to the term "simple perennial." Lastly, while many household flowers can be perennials, not all are, so that choice does not adequately encapsulate what defines a simple perennial plant. Thus, the correct answer highlights the fundamental characteristics that classify a plant as a simple perennial.
