“Mary Washington” asparagus officinalis is one of the older and most common asparagus varieties. This perennial vegetable is harvested in spring, producing a high yield of tender spears from a rhizome crown. Planting from seed delays harvest for an additional year, so asparagus is often planted from one-year-old crowns, producing a small crop in three years and heavier yield for up to 30 years.
