Asparagus (Asparagus officinalis) is a hardy perennial vegetable native to the seacoasts of Europe and eastern Asia, where it has been cultivated for over 2,000 years. It was a well-known and valued vegetable to both the Greeks and Romans. Early settlers brought asparagus to North America, where it has been grown in home gardens since colonial times.
Asparagus plants are dioecious, meaning that male and female flowers are produced on separate plants. The flowers are small, bell shaped, and whitish green.
Tasty spears are dark green with purple color at the tips. Heavy yields
The spears, if not harvested, develop into ferns 4-6 feet tall. Carbohydrates and other compounds necessary for plant growth and development are produced in the ferns throughout the growing season.
Taking 3-6 weeks to germinate and slow to get going, the asparagus seeds should be sown indoors 12 to 14 weeks before the target seedling set-out date, which should be after the danger of frost has passed.
