Indeciduous, which refers to a plant that retains its leaves for more than one growing season, has several synonyms. One such synonym is evergreen, which commonly describes coniferous trees and shrubs that keep their foliage throughout the year. Another synonym is persistent, which describes plants that maintain their leaves for an extended period but eventually shed them. Other terms that can be used as synonyms for indeciduous include non-deciduous, non-seasonal, green year-round, and perennial foliage. These synonyms help to clearly describe and differentiate this category of plants from deciduous plants, which shed their leaves annually, thereby transforming their appearance.
