There are two types of plants; annuals and perennials.Annuals, are plants that complete their life cycle, from germination to the production of seed, within one year, and then die. Summer annuals germinate during spring or early summer and mature by autumn of the same year.Perennials are a must for the foundation of every flower border. They contain a wide variety of plant groups. The splendid colours look best planted in large groups or in groups of three or five. Also known as ‘herbaceous perennials’, these indispensable garden subjects will surprise you year after year with their fine foliage and floral splendour. The roots take water and nutrients from the soil to feed the top leaves, stems and flowers. The leaves and flowers reappear in full glory every year. Many of these plants even produce flowers for cutting. The best time for transplanting perennials is in the autumn.
