What is a primary characteristic of perennials?

Perennials are defined by their ability to live for more than two years, and a primary characteristic is indeed that they die back to the ground in the fall and regrow from their root systems in the spring. This growth cycle allows them to thrive year after year, as they can take advantage of seasonal changes, making them a popular choice in landscaping for providing consistent bloom and foliage over multiple seasons.

In contrast to annuals, which complete their life cycle in one season, perennials have a longer lifespan and can offer more permanence in a garden. Contrary to options that suggest they do not bloom or require frequent replanting, perennials can produce vibrant flowers and require less maintenance over time compared to annual species, as they do not need to be replanted each season.
