What is a perennial plant?
Perennial Plant Definition– A plant that is capable of living for more than two years.
Ideal Home Garden Explains
Unlike annuals and biennials, perennial plants can survive longer than two years. Rather than dying after completing their life cycle within the year, perennials simply lose their blooms and/or leaves during cold winter months, and regrow during warmer spring and summer weather. Common perennials include trees and shrubs, roses, lilies, sage, daffodils, hibiscus, ferns and asters. See Perennial Garden Guide.
