Herbaceous perennials are plants that live for more than two years and have non-woody stems. They typically die back to the ground in winter and regrow in spring from their root systems. Common examples include daylilies, hostas, and peonies. These plants are valued for their ability to provide color and texture in gardens year after year. Unlike annuals, which complete their life cycle in one growing season, herbaceous perennials can thrive in various climates and soil types. They often require less maintenance once established, making them a popular choice for gardeners looking for long-lasting beauty.
