Asparagus (Asparagus officinalis) is an herbaceous perennial that grows to a height of three or four feet from stout rhizomes. It is native to Eurasia and Africa where it has been used as a vegetable and for medicinal purposes since Roman times. It was likely introduced to North America in the 1600s or 1700s. It is now widely planted in gardens and has also escaped the garden to become known as wild asparagus.
