Perennials are plants that survive for two years or more, blooming annually after maturity. Common perennials include peonies, bellflowers, daylilies, and Platycodon grandiflorus. The underground parts of perennials can overwinter in the soil, resprouting and growing again in spring. Besides their beautiful flowers and foliage, perennials also exhibit unique overall plant posture and charm.

Introduction to Perennials

Perennials can be utilized for many years, boasting a long观赏 period, high garden usage value, and outstanding greening effects. They play a significant role in the development of environmentally friendly and resource-saving urban green landscapes.

Perennial flowers can be divided into two main categories: those that are more frost-tolerant and those that are not. The former can be planted outdoors, while the latter require cultivation in greenhouses. Propagation primarily involves division, usually during the dormant period, with species with fewer new buds able to be propagated through cuttings or grafting. Seed propagation is more commonly used for breeding new varieties.

When planting perennials, it's essential to deeply till the soil and apply a generous amount of organic fertilizers to ensure optimal soil conditions for a prolonged period. Perennials require well-draining soil.
