Perennial
Perennial in general means something that is enduring, long lasting or indeed constant or perpetual.
It is most commonly used in reference to plant species that persist for several years usually with new herbaceous growth. Woody perennials, include vines, shrubs, and trees, though these generally stop growing during winter and in drought. Asters, irises, tulips, and peonies are garden perennials, remaining active throughout the year, or for long periods.
In horticulture a perennial plant is one that lives for more than two years, often used to differentiate a plant from shorter-annuals and biennials.
