Despite coming from the same plant, there are variations in nutritional value between green and white asparagus. Green asparagus tends to have higher levels of nutrients, such as protein, as well as ascorbic acid, calcium, thiamin, and niacin. White asparagus generally has lower antioxidant content than green spears.
Did you know that before harvesting, asparagus spends up to three years in the ground? First the seed is planted, then the plant is harvested to give more room for growth, and then it is harvested for a full season once it is fully matured.
