Perennial flowers are plants that live for more than two years. They are often used to differentiate a plant from shorter-lived annuals and biennials. Unlike annuals, which complete their life cycle in a single year, perennials live for three years or longer. Perennials invest more resources than annuals into roots, crowns, and other structures that allow them to live from one year to the next. They often have a competitive advantage because they can commence their growth and leaf out earlier in the growing season, and can grow taller than annuals, in doing so they can better compete for space and collect more light. Perennials that are cultivated include woody plants like fruit trees, as well as herbaceous plants like flowers and vegetables.

Perennial flowers are a popular choice for gardeners because they require very little maintenance after initial planting and come back every year. They bloom for at least two seasons and provide a sense of continuity from year to year. There are many variations of top perennials to choose from, including foliage thats purple, pink, yellow, blue, white, and red. Some examples of popular perennial flowers include Monarda Didyma (Bee Balms), peonies, catmint, Penstemon, and Bee Balm.
