Especially in Germany, the so-called “White Gold” is very popular–it’s even said to have remarkable health benefits. But asparagus isn’t just white. The green variety is also increasingly appreciated here. The question remains: Which asparagus is actually healthier?

Differences Between White and Green Asparagus
With over 300 different varieties and present in many parts of the world for ages, asparagus is used as food, a garden plant, or even a supposed remedy.1 However, as a food plant, it’s really only distinguished between two types: green and white asparagus.2 Still, the variety is vast. In France, for example, the purple hybrid is becoming increasingly popular.
Cultivation
The different colors of asparagus result from various cultivation methods. White asparagus grows entirely underground–protected by opaque plastic sheeting stretched over the mounds of earth. This keeps it colorless. Green asparagus, on the other hand, grows above ground and is exposed to the sun throughout its growth phase. The light causes it to produce chlorophyll, giving it its green color.
Purple asparagus is also botanically classified as green asparagus. It is harvested relatively early like white asparagus and grows mostly underground. Its violet color develops due to limited light exposure.
Harvest Time
The harvest time also differs: White asparagus is typically harvested between mid-April and June 24. Green asparagus can often be picked as early as late March or early April.
The plant itself–Asparagus officinalis–belongs to the lily family and is a perennial shrub. It takes about three years from planting to the first harvest. After that, the plant can produce the coveted spears for up to ten years. Since harvesting is labor-intensive and cultivation requires a lot of time, asparagus is considered a relatively expensive vegetable.

Preparation and Taste
White asparagus is often described as mild or rather neutral, while green asparagus has a stronger, slightly nutty flavor. This is also due to the preferred preparation: Green asparagus is often sautéed or roasted in the oven, which brings out intense roasted flavors. White asparagus is traditionally boiled or steamed.
Another difference lies in handling: White asparagus is thicker and must be peeled completely from top to bottom–the tender tip is left untouched. Green asparagus, however, is more delicate and usually only needs to be peeled or slightly trimmed at the lower third.
Asparagus is also edible raw–if it’s of good quality. However, you should ensure it doesn’t have woody or bitter spots, which indicate a lack of freshness.
A special asparagus pot, where the spears are cooked standing up, is best for cooking–this keeps the delicate tips intact. Cooking time ranges from eight to 15 minutes, depending on thickness. Green asparagus generally requires less time. The cooking water can be enhanced with salt, a pinch of sugar, and a bit of lemon juice.3
What Makes White Asparagus Healthy
White asparagus provides many important micronutrients–including vitamin C, vitamin E, potassium, calcium, magnesium, and folic acid. These substances perform various functions in the body, such as supporting the immune system, metabolism, and nerve function.
Another advantage: Asparagus is very low in calories. 100 grams contain only about 18 kilocalories. At the same time, the fiber it contains ensures you feel full for a long time–this can prevent cravings for unhealthy snacks.4
Green Asparagus Even Healthier
In terms of vitamin content, green asparagus surpasses white: it contains more vitamin C and provitamin A, which are important for the eyes and immune system. The green variety also usually has higher levels of chlorophyll, iron, and magnesium.
And the Purple Asparagus?
Purple asparagus, which botanically lies between white and green asparagus, is more similar to the white variety in terms of nutritional values. Its color comes from the polyphenols it contains. According to a meta-analysis, these secondary plant compounds–if consumed abundantly–may have a preventive effect on the risk of type 2 diabetes.5 Due to its mild-sweet taste and striking color, purple asparagus is increasingly appreciated–especially in gourmet cuisine.

Is Asparagus a Remedy?
Greeks, Romans, and the high cultures in Asia already knew about the healthy effects of asparagus plants on humans. This goes beyond consumption as food. Back then, cultural circles also used asparagus as medicine. Did they know something we didn’t?
It is generally believed that secondary plant compounds have positive effects on human health. A study at least suggests that asparagus could lower cholesterol levels and thus have positive effects on blood pressure.6 However, since the study was conducted on rats, the results cannot be directly applied to humans. Other theories also suggest that asparagus helps the body with water retention and against toxins. While it’s true that the high water content and fiber promote digestion and have a diuretic effect, there is no scientific evidence for an actual detoxifying effect.
Therefore, the plant doesn’t really go beyond its status as a mythical home remedy. Nevertheless, you can enjoy asparagus more often during the season, as it is indeed healthy.
Conclusion
Whether green, white, or purple–asparagus is a healthy vegetable in any form. If you prefer it particularly nutrient-rich, green asparagus is the best choice. But the classic white asparagus also scores with important vitamins, minerals, and few calories. The choice is a matter of taste–health-wise, you can’t go wrong with any variety.
