Secondary Growth: One of the most remarkable features of woody perennials is their ability to undergo secondary growth. This process involves the thickening of the stem and the formation of new layers of wood and bark. Secondary growth is responsible for the increase in girth and strength of the stem, enabling the plant to support its own weight and resist external forces.
Reproduction: Reproduction in woody perennials typically involves the production of flowers and fruits. These reproductive structures are essential for the continuation of the species. Some woody perennials rely on wind or animals for pollination, while others self-pollinate. Once fertilized, the plant produces seeds, which can be dispersed by various means, including wind, animals, or gravity.
