Purple asparagus originated in Italy's Liguria region but has since been cultivated in many other countries.

What's the difference between green and purple asparagus?

Like their green and white cousins, purple asparagus can vary in stalk thickness. The thicker stalks are woodier, more pungent, meaty and fibrous, while the thinner ones are soft, tender and crunchy.

If you have steered away from including asparagus as part of your meals due to their earthiness or grassiness, then you might want to give it a second chance, particularly with purple asparagus.

Like its white counterpart, purple asparagus is mild in flavor but sweeter than green asparagus. It has a higher content of natural sugars than other asparagus varieties.

Purple asparagus is also nuttier in flavor. When cooked, these purple, stalky vegetables resemble a blend of barley, almonds and artichokes.

Health Benefits of Purple Asparagus

Nutritionally, asparagus is low in sodium and calories and is fat- and cholesterol-free. It is also an excellent source of vitamin K, an essential nutrient for blood clotting. Every half-cup serving (or about 6 spears) of asparagus contains more than half of the daily recommended intake of vitamin K, based on a 2,000-calorie diet. 

Undoubtedly a nutrition powerhouse, every 90 gram-serving of purple asparagus also provides more than one-third of your daily folate needs. This essential B vitamin helps prevent anemia and keeps the heart healthy. Folate is also a vital nutrient for women considering pregnancy because it helps to reduce the risk of neural tube defects in babies in the early weeks of their development.

Asparagus is also a source of dietary fiber, an important nutrient for supporting a healthy gut and decreasing the risk of chronic illnesses like heart disease and diabetes. In addition, the stalky vegetables also contain thiamin and riboflavin, both essential for growth and development as well as for an energetic metabolism.

But what makes purple asparagus stand out from their green and white cousins is its abundance of anthocyanins, a pigment that gives them the purple hue. Anthocyanins are also a powerful antioxidant that may have anti-inflammatory properties and protect against heart disease, diabetes and Parkinson's disease.
