Field greens, also known as mesclun mix or spring mix, have become a staple in salads, side dishes, and even as a garnish. But what exactly are field greens? The term isn’t as straightforward as it might seem. It encompasses a variety of young, tender leafy greens harvested at an early stage of growth. Understanding what constitutes field greens can help you make informed choices at the grocery store, appreciate their nutritional benefits, and even grow your own.
Defining Field Greens: Beyond the Bag
The term “field greens” is a broad one. It doesn’t refer to a single type of plant. Instead, it describes a mixture of various young, tender leafy greens, often harvested within a few weeks of sprouting. The composition of a field greens mix can vary widely depending on the supplier, season, and geographical location. This variability is part of their appeal, offering a diverse range of flavors and textures in a single salad.
Originally, “mesclun” referred to a specific mix of wild greens from the Provence region of France, typically including arugula, chervil, lettuce, and endive. Today, the term “mesclun” is often used interchangeably with “field greens,” though the specific greens included might differ. Spring mix is another common term, suggesting the tender, early-season growth of these greens.
Key Characteristics of Field Greens
Several characteristics define what qualifies a green as a field green. These include:
- Young and Tender: Field greens are harvested at a young stage, typically when they are only a few inches tall. This early harvest results in a more delicate texture and milder flavor compared to mature greens.
- Variety of Leaves: Field greens mixes are almost always composed of multiple types of greens. This diversity ensures a more complex flavor profile and a wider range of nutrients.
- Freshness: Freshness is paramount. Field greens are best consumed shortly after harvesting to maintain their crispness and flavor.
- Ready to Eat: They are usually pre-washed and ready to eat, offering convenience for consumers.
Common Greens Found in Field Green Mixes
The specific greens included in a field greens mix can vary, but some are more common than others. Knowing these common components can help you identify the flavors and textures you prefer.
Lettuce Varieties
Several types of lettuce frequently appear in field greens mixes:
- Red Leaf Lettuce: Adds a slightly sweet and mild flavor, along with a vibrant red color.
- Green Leaf Lettuce: Offers a mild, slightly bitter flavor and a crisp texture.
- Romaine Lettuce (Baby Romaine): Provides a refreshing, slightly crunchy texture and a mild, slightly nutty flavor.
- Butter Lettuce (Baby Butter): Delivers a delicate, buttery flavor and a soft, almost velvety texture.
Other Leafy Greens
Beyond lettuce, other greens add distinct flavors and nutrients:

Using Field Greens in the Kitchen
Field greens are incredibly versatile and can be used in a variety of culinary applications.
Salads
The most common use for field greens is as the base for salads. Their diverse flavors and textures pair well with a wide range of dressings, toppings, and proteins. They can be used as a simple side salad or as the foundation for a more elaborate main course salad.
Sandwiches and Wraps
Field greens can add a fresh, crisp element to sandwiches and wraps. They provide a lighter and more nutritious alternative to iceberg lettuce.
Garnishes
A sprinkle of field greens can add a pop of color and freshness to various dishes, from soups and stews to grilled meats and vegetables.
Smoothies
While not as common, field greens can be added to smoothies for an extra boost of nutrients. Spinach and other mild-flavored greens are best suited for this purpose.
Sautéed Greens
Field greens can be quickly sautéed with garlic and olive oil for a simple and flavorful side dish. Be careful not to overcook them, as they will wilt quickly.
Growing Your Own Field Greens
Growing your own field greens is a rewarding experience. It allows you to control the varieties you include, ensures maximum freshness, and can be a fun and educational activity.
Easy to Grow
Field greens are relatively easy to grow, even for beginners. They can be grown in gardens, raised beds, or even containers on a balcony or patio.

One of the biggest advantages of growing field greens is their quick harvest time. Many varieties can be harvested within a few weeks of planting.
Succession Planting
To ensure a continuous supply of fresh greens, practice succession planting. This involves planting new seeds every few weeks.
Ideal Conditions
Field greens prefer cool weather and well-drained soil. They also need adequate sunlight, but can tolerate partial shade.
Field Greens vs. Other Greens: Understanding the Differences
It’s helpful to understand the differences between field greens and other common types of greens, such as spinach, kale, and iceberg lettuce.
Field Greens vs. Spinach
While baby spinach is often included in field greens mixes, mature spinach has a tougher texture and a stronger flavor. Field greens offer a more diverse range of flavors and textures compared to spinach alone.
Field Greens vs. Kale
Kale is a hardy green with a robust flavor and a slightly bitter taste. It requires more cooking time than field greens and is typically not eaten raw. Field greens are much more tender and mild.
Field Greens vs. Iceberg Lettuce
Iceberg lettuce is known for its crisp texture and mild flavor. However, it is relatively low in nutrients compared to field greens. Field greens offer a significantly higher nutritional value and a more complex flavor profile.
In conclusion, field greens represent a diverse and nutritious mix of young, tender leafy greens. Understanding what constitutes field greens, their nutritional benefits, and how to properly select and store them can elevate your salads and other culinary creations. Whether you buy them at the store or grow your own, field greens are a delicious and healthy addition to any diet.
What exactly are field greens?
Field greens are a mix of young, tender leaves harvested from a variety of plants. Unlike head lettuce, which grows into a compact ball, field greens are cut at an early stage of growth, typically when they are just a few inches tall. This early harvest results in a delicate texture and a milder flavor profile compared to their more mature counterparts.
The specific greens included in a field green mix can vary depending on the grower, the season, and the region. However, some common components include baby spinach, romaine lettuce, red leaf lettuce, green leaf lettuce, oak leaf lettuce, arugula, mizuna, and radicchio. The blend offers a diversity of nutrients, flavors, and textures, contributing to a more complex and enjoyable salad experience.
How do field greens differ from spring mix?
While often used interchangeably, field greens and spring mix have subtle differences. Field greens traditionally emphasize tender, young leaves harvested directly from the field, prioritizing a mix of different lettuce types and leafy greens with delicate flavors. The composition focuses on a balanced combination of mild and slightly peppery notes.
Spring mix, on the other hand, is a broader term that can include a wider variety of greens, sometimes incorporating herbs and more robust leaves. The selection isn’t solely focused on “field-grown” elements; instead, it’s a curated blend aimed at offering a diverse mix of flavors and textures. Therefore, while all field greens could be considered a spring mix, not all spring mixes qualify as field greens due to the variability in their composition.
What are the nutritional benefits of consuming field greens?
Field greens offer a rich source of vitamins and minerals crucial for maintaining optimal health. They are particularly high in vitamins A and C, which are potent antioxidants that help protect the body against cell damage. They also contain valuable amounts of vitamin K, essential for blood clotting and bone health, along with folate, an important B vitamin that supports cell growth and development.
Beyond vitamins, field greens provide a significant source of dietary fiber, which aids in digestion and promotes a feeling of fullness, contributing to weight management. They also contain minerals like potassium, important for regulating blood pressure, and calcium, vital for strong bones and teeth. Their diverse mix ensures a broad spectrum of nutrients beneficial for overall well-being.
How should I properly wash and store field greens?
Washing field greens thoroughly is crucial to remove any dirt or debris before consumption. The best method involves placing the greens in a large bowl filled with cold water and gently agitating them to loosen any impurities. After soaking for a few minutes, carefully lift the greens out of the water, leaving any sediment behind. Repeat this process until the water remains clear.
To properly store field greens, gently dry them using a salad spinner or by patting them with paper towels. Place the dried greens in a container lined with a clean paper towel to absorb any excess moisture. Store the container in the refrigerator crisper drawer. This method helps to keep the greens fresh and crisp for several days, preventing them from becoming wilted or slimy.
What are some creative ways to use field greens beyond salads?
While salads are a classic use for field greens, their versatility extends far beyond. They can be incorporated into a variety of dishes to add a boost of flavor and nutrients. Consider using them as a base for grain bowls, pairing them with quinoa, brown rice, or farro, along with roasted vegetables, proteins, and a flavorful dressing.
Field greens can also be added to sandwiches and wraps for a fresh, crisp element. They can be lightly sautéed with garlic and olive oil as a side dish, or even blended into smoothies for a hidden dose of greens. Another creative application is using them as a topping for pizzas or flatbreads after they’ve been baked, adding a vibrant touch of freshness and color.
Are there any potential downsides to eating field greens?
While generally safe and healthy, there are a few potential downsides to consider when consuming field greens. As with any raw produce, there is a risk of contamination with bacteria like E. coli or Salmonella, especially if the greens are not properly washed. Choosing pre-washed greens can reduce this risk, but it’s still important to handle them carefully.
Another potential issue is pesticide residue, particularly if the greens are not organically grown. Thoroughly washing the greens before consumption can help minimize this risk. Additionally, individuals with certain medical conditions or those taking blood-thinning medications should be mindful of their vitamin K intake from leafy greens like field greens, as they can affect blood clotting.
How can I choose the freshest field greens at the grocery store?
Selecting the freshest field greens at the grocery store involves careful observation. Look for greens that have vibrant color, whether green, red, or a mix. Avoid packages with wilted, slimy, or yellowing leaves, as these are signs of age and spoilage. Check the “use by” or “sell by” date to ensure the greens are still within their optimal freshness window.
Examine the package for any signs of damage or excessive moisture. A sealed bag with condensation can indicate that the greens are starting to deteriorate. Finally, gently feel the bag; the greens should feel light and airy, not heavy or compacted. Opting for organic field greens can minimize exposure to pesticides, but all greens should be washed thoroughly before consumption regardless.
