Perennial plants are herbaceous plants which die back to the ground during winter and grow back in spring. Some can be left undisturbed for years while others need to be divided every few years to maintain their vigour. You can find a perennial plant for any situation, whether it's a stone wall or a shady corner. Some are grown for their flower displays, others for their beautiful foliage. Evergreen perennials and half-shrubs are included in this category.
