The grass that grows on most lawns is a perennial. This is because it grows, reproduces, and flourishes over and over and it still stays on your lawn. An example to prove it is a perennial is that if you had a lawn full of green grass and about 2 years later it is still there then it is not a biennial, and if you had a lawn full of green grass and the growing season is over and it is still there then it is not an annual.
