A perennial plant or simply perennial is a plant that lives for more than two years. The term is often used to differentiate a plant from shorter-lived annuals and biennials.
Wed Apr 22, 2009 3:22 pm. Perennial is what lawns are normally. It means several life cycles or continual growth. Annual grass only grows for one season and when conditions are no longer favorable (seasonal temps/moisture), it dies out (completing its life cycle) and doesn't return the following year. Indiana is not an area that supports green grass year round.
