Is Cress the Same as Watercress? A Detailed Comparison

•
3 min read

While both share a similar pungent, peppery flavor and belong to the same plant family, cress and watercress are not the same plant. The term "cress" can refer to several related plants, including garden cress and land cress, while watercress is a distinct aquatic species with its own unique characteristics.

Quick Summary

Despite their peppery taste, cress and watercress are distinct plants differing in genus, habitat, and flavor intensity. One thrives in soil, while the other grows in water. Their contrasting growth habits and subtle flavor profiles define their culinary uses.

Key Points

  • Different Species: Cress and watercress are not the same plant, belonging to different genera within the Brassicaceae family.

  • Growing Conditions Vary: Watercress is an aquatic plant requiring flowing water, while common garden cress grows easily in soil.

  • Distinct Flavor Profiles: Garden cress typically offers a more intense, pungent peppery flavor, whereas watercress has a milder, fresh taste.

  • Different Textures: Watercress has delicate, succulent stems and leaves, while upland cress is heartier and more robust.

  • Best For Different Uses: Watercress is ideal for delicate applications like soups and salads, while garden cress is excellent for adding a fiery kick to sandwiches.

  • Nutritionally Unique: Although both are healthy greens, their specific nutritional content, including vitamins and minerals, varies significantly.

Botanical Differences: The Cress Family Tree

Although they are often confused, cress and watercress belong to different genera within the same family, Brassicaceae (the mustard family). This biological distinction accounts for their differing growth habits, appearances, and flavor nuances. Watercress's scientific name is Nasturtium officinale, while the most common variety, garden cress, is Lepidium sativum. Upland cress, or American cress, which is often sold as a watercress substitute, is a different species altogether, Barbarea verna. This shared family is why they have a similar pungent, peppery taste profile, a defensive mechanism against predators that humans happen to enjoy.

Watercress: The Aquatic Green

Watercress is a semi-aquatic or aquatic perennial plant that thrives in flowing water. This makes its cultivation a very different process compared to its land-based cousins. Historically, it was foraged from streams, though most commercially sold watercress is now grown hydroponically in water beds. It has distinctive hollow, buoyant stems and round, fleshy leaves. This growth habit explains its delicate texture and propensity to wilt quickly, making it best used fresh.

Garden Cress: The Fast-Growing Favorite

Garden cress is an annual herb known for its incredibly fast growth cycle—often ready to harvest in a little over a week as microgreens or sprouts. It is grown in soil, and its taste is often more pungent and fiery than watercress, especially when mature. The leaves of garden cress are typically smaller and frillier than watercress, and it lacks the hollow, succulent stem of its aquatic relative.

Upland Cress: The Land-Dwelling Alternative

Upland cress is a land-based alternative to watercress that is also a member of the Brassicaceae family. Also known as American cress, its leaves are more frilly and serrated than watercress and it has a taste that is often described as peppery like arugula. It is more durable and less prone to wilting than watercress, making it a robust substitute for dishes where watercress might be too delicate.

Comparison Table: Cress vs. Watercress

Feature Watercress Garden Cress Upland Cress
Botanical Name Nasturtium officinale Lepidium sativum Barbarea verna
Growth Environment Aquatic or semi-aquatic (flowing water) Terrestrial (moist soil, fast-growing) Terrestrial (drier soil, tolerant)
Appearance Round, dark green leaves; hollow stems Smaller, frilly leaves Serrated or jagged leaves
Flavor Milder, peppery, and fresh More pungent, fiery, and tangy Peppery, often compared to arugula
Texture Delicate and succulent; wilts easily Tender, soft leaves Sturdy and crunchy; holds up well
Harvest Time Slower to mature, harvested when mature Very fast (7-10 days for sprouts) Medium speed, harvested immature for best flavor
Culinary Use Soups, salads, sandwiches, garnishes Sprouts for sandwiches, salads, garnishes Hearty salads, sandwiches, garnishes

Taste, Texture, and Culinary Applications

The primary reason for distinguishing between these greens in the kitchen is their differing textures and flavor intensity. Watercress offers a fresh, mild peppery bite with a tender, delicate texture that is perfect for pureed soups or salads where it won't be overpowered. Garden cress provides a more intense, mustard-like spiciness in its young sprout form, ideal for adding a sharp kick to egg sandwiches or salads. Upland cress, with its tougher stems and heartier leaves, holds up better to heat and dressing, making it a good choice for stir-fries or robust salads.

Nutritional Comparison

While both offer significant health benefits, their specific nutritional profiles differ. Both are part of the cruciferous vegetable family and are rich in antioxidants and vitamins A, C, and K. However, some studies have noted that garden cress can contain significantly higher levels of certain nutrients, such as folate, than watercress. Watercress, on the other hand, is particularly renowned for its high antioxidant content, which has led to some studies exploring its potential cancer-preventive properties.

Conclusion

In summary, while the peppery taste of watercress and other varieties of cress might seem similar, they are not the same plant. They are distinct species within the same broader family, each with unique growing requirements, botanical features, and culinary applications. Understanding these differences allows cooks and gardeners to appreciate their individual characteristics, ensuring the right type is chosen for flavor, texture, and growth environment.

Frequently Asked Questions

The primary difference is their growing environment and species. Watercress is an aquatic plant (Nasturtium officinale) that grows in water, while other types of cress, like garden cress (Lepidium sativum), grow in soil.

While both have a peppery taste, they differ in flavor intensity and texture. Garden cress has a stronger, spicier flavor and a more delicate texture. For a more comparable substitute, upland cress (Barbarea verna) is often recommended due to its similar peppery bite and slightly more robust leaves.

Yes, both cress and watercress are part of the Brassicaceae family, also known as the mustard or cabbage family. This shared lineage is why they possess a similar peppery flavor profile.

Both are highly nutritious, containing antioxidants, vitamins, and minerals. However, nutritional content can vary. Some sources note garden cress is particularly high in certain nutrients like folate, while watercress is known for its high antioxidant levels.

Watercress leaves are typically rounder and have hollow, succulent stems, while garden cress leaves are smaller and more frilly or serrated. The growth habit is also a clue: watercress has floating roots, while garden cress is rooted in soil.

Upland cress is a land-based alternative to watercress that is more robust and less prone to wilting. Also known as American cress, it is often used as a substitute in salads and sandwiches.

The genus name for watercress is Nasturtium. However, the common garden flower called nasturtium (Tropaeolum majus) is a different, unrelated plant, though it also has an edible peppery flavor.
