A perennial is a plant that lives for more than two years. Perennials are flowering plants which grow and bloom over the spring and summer and then die back every autumn and winter. They typically grow structures that allow them to adapt to living from one year to the next through a form of vegetative reproduction rather than seeding. Perennial plants often have deep, extensive root systems which can hold soil to prevent erosion, capture dissolved nitrogen before it can contaminate ground and surface water, and outcompete weeds. They grow very well in conditions that are poor in resources due to their earlier emergence in the spring, and the development of larger root systems which can access water and soil nutrients deeper in the soil.
