perennikasveja

Perennikasveja, also known as perennial plants, are a category of plants that live for more than two years. Unlike annuals, which complete their life cycle in a single growing season, or biennials, which live for two years, perennials return year after year. This longevity is often due to specialized storage organs, such as roots, bulbs, or rhizomes, which allow them to survive through dormant periods like winter or drought and regrow from the same root system.

The term "perennial" is a broad classification and encompasses a vast diversity of plant types, including herbaceous plants, shrubs, and trees. Herbaceous perennials die back to the ground in the fall or winter, with their top growth withering, but their roots remain alive and produce new shoots in the spring. Woody perennials, such as shrubs and trees, retain their above-ground woody stems throughout the year, though they may shed their leaves seasonally.

In horticulture and gardening, perennial plants are highly valued for their ability to provide continuous beauty and structure in a landscape. Once established, they require less frequent replanting than annuals, making them a more sustainable and often less labor-intensive choice. Their varied bloom times, foliage textures, and heights offer a wide range of design possibilities for gardens. Many perennial species are also important components of natural ecosystems, providing habitat and food for wildlife.
