What term describes plants that live for more than two years or growing seasons?

The term that describes plants that live for more than two years or growing seasons is "perennial." Perennial plants have the ability to grow back year after year, often from the same root system, which allows them to thrive through various seasons and conditions. This characteristic distinguishes them from annual plants, which complete their life cycle in one growing season, and biennial plants, which typically take two growing seasons to complete their life cycle.

Deciduous refers to trees and shrubs that lose their leaves annually rather than the lifespan of the plant itself, so it doesn't fit the criteria of longevity over multiple growing seasons. Understanding these distinctions is crucial in horticulture and pest management, as different plant types require varied care and treatment strategies.
