|A perennial is any plant that lives for three or more years. There are woody perennials and herbaceous perennials. Woody perennials can be evergreen or deciduous. Evergreen perennials retain their leaves all winter long; deciduous perennials lose their leaves in the fall and grow new leaves in the spring. Herbaceous perennials die down in the cold weather and sprout new stems and leaves in the spring time. Hope this answers your question!
