Herbaceous perennials are plants with soft green stems that usually die in the winter, while their roots thrive underground allowing regrowth in the spring. Most perennials are herbaceous. They are a great foundation for your garden, bringing many showy blooms and good ground cover. What is a perennial? Perennials are ornamental plants that stick around from year to year. Do not confuse this longevity, however, with an infinite life span. They do not stay at their peak forever. Observe your herbaceous perennials, and replace them when needed. Most last about two to three years, and some longer if they are natural to your environment. Low Maintenance Herbaceous Perennial or Not? Do not take it for granted that a seemingly low maintenance herbaceous perennial is actually little care for your situation. You will need to check your environment against your choice of perennial. Consult with your local nursery or your experienced neighbors if you are a beginner. For example, if your desired perennial is prone to pests and diseases affecting your region, you will need to take time and spray often. If it grows faster than you have time to divide, it will again take more of your time. You also need to be mindful of the climate.
