Asparagus may be one of the most costly vegetables at the supermarket. I know this because my daughter loves it; however, this perennial vegetable may be one of the easiest to grow. 

Perennials are plants that live for many growing seasons. They dieback in the winter and grow back in the spring from the same root system. Asparagus plants will produce for 20 years, if not longer than, and provide tender green spears every spring. It will take two to three years before the asparagus reaches full production.Â
