Perennial Plants- A perennial plant is a plant that comes back year after year from its roots. Some perennial plants are short lived for only a couple years, while other perennials live for many years. Perennial plants bloom generally for a short period of time during the growing season and then are finished flowering. Perennials can occasionally rebloom during the season if they are trimmed back and are able to reflush and create a second round of blooms. Plants that are classified as perennials may not be a perennial in all areas of the county. Make sure that you choose a perennial plant that is in your hardiness zone for it to come back year after year. Perennial landscaping will offer many seasons of enjoyment.
