Perennials are distinguished by their ability to return year after year. Unlike annuals, which complete their life cycle in one growing season, or biennials, which bloom in their second year, perennials typically establish a root system that allows them to survive through various seasons. During the growing season, they may die back to the ground in winter but regenerate from their roots in spring. This regenerative characteristic is what allows perennials to provide consistent blooms and foliage year after year, making them a popular choice in many gardens for their longevity and reliability.
