Garden Cress: Nutritional Values, Benefits, and Why Home Cultivation Makes a Difference

Garden cress often ends up in many kitchens merely as a garnish on bread. Yet, it is one of the most nutrient-rich plants you can grow at home in Germany – and one of the fastest.

In short: 100g of fresh garden cress provides more vitamin C than an orange, covers multiple times the daily requirement of vitamin K, and contains iron, calcium, folic acid, and natural mustard oils – all with only 32 calories. It is most beneficial when harvested just before eating, as vitamin C and mustard oils degrade quickly after harvesting.

Here are the reliable nutritional values, what they mean for everyday life, how it tastes, and why growing it fresh makes the biggest difference.

Quick answer: Garden cress (Lepidium sativum) is one of the most nutrient-dense plants for the windowsill. It contains a lot of vitamin C, vitamin K, iron, calcium, and natural mustard oils, has a slightly sharp and spicy taste, and goes well with bread, salads, soups, dips, and pesto. If you're looking for a direct comparison of varieties, you'll find it in the "Which Cress is Healthiest?" guide.

What's in Garden Cress? Garden Cress Nutritional Values per 100 g, Fresh

The following values are from the USDA FoodData Central database – the most widely used reference for food ingredients worldwide.

Note: mg = milligram (1/1000 g). µg = microgram (1/1,000,000 g). For vitamin K and A, this is often enough for the entire daily requirement.

What's in it? How much per 100g? What does it mean for you?
Vitamin C 69 mg (more than in an orange) Strengthens the immune system, aids iron absorption
Vitamin K 541 µg (covers daily requirement multiple times) Important for bones and blood clotting
Vitamin A 346 µg (approx. half of daily requirement) Good for eyes and cell growth
Iron 1.3 mg Transports oxygen in the blood
Calcium 81 mg (similar to a small glass of milk) Keeps bones and teeth strong
Folic Acid (Vitamin B9) 80 µg (≈ 20 % of daily requirement) Supports cell division, important during pregnancy
Potassium 606 mg (≈ like half a banana) Good for heart and blood pressure
Natural Mustard Oils contained Provide typical taste, act as antimicrobials
Calories approx. 32 kcal Many nutrients, few calories – ideal as a daily topping

What are the benefits of Garden Cress Vitamin C and Vitamin K for the body?

Garden cress is not a miracle cure. But it is one of the most nutrient-dense foods that can be easily incorporated into everyday life.

More Vitamin C than an orange

100g of garden cress contains 69mg of vitamin C, while a medium-sized orange contains about 53mg. Vitamin C supports the immune system and helps the body absorb plant-based iron more effectively. Important: Vitamin C is sensitive to heat – always eat garden cress fresh and raw.

Plenty of Vitamin K – good for bones and blood clotting

Garden cress is one of the best plant-based sources of vitamin K. 100g covers an adult's daily requirement multiple times over. Vitamin K plays a central role in bone metabolism and blood clotting.

Natural mustard oils – the reason for the taste

The slightly sharp taste comes from glucosinolates, which are converted into mustard oils when chewed – the same compounds found in mustard and horseradish. They are being researched for their antimicrobial properties.

Iron and folic acid – good for blood and cells

Plant-based iron is better absorbed when vitamin C is consumed at the same time. Garden cress provides both in one plant. Folic acid is particularly relevant during pregnancy.

Nutrient-dense with only 32 calories per 100g

Garden cress is among the foods with the highest nutrient density per calorie – ideal as a daily topping.

Important: Garden cress is a food, not a medicine. It can be part of a balanced diet but does not replace medical treatment.

How does garden cress taste and what does it go with?

Garden cress tastes slightly spicy and aromatic, similar to arugula, but fresher and less bitter. The flavor comes from its natural mustard oils – pleasantly intense without being overpowering.

What is garden cress suitable for?

  • Bread and sandwiches: the classic. Sprinkled fresh, it immediately adds flavor.
  • Salads: as a microgreen base or an addition to leafy salads.
  • Soups: sprinkled on just before serving, do not cook.
  • Dips and spreads: puréed with cream cheese or quark.
  • Frankfurter Grüne Soße (Green Sauce): Garden cress is one of the seven traditional herbs.
  • Pesto: as a spicy alternative to basil.
  • Smoothies: in small quantities for a nutrient-rich green.

Tip: Never heat garden cress. Heat destroys the mustard oils and much of the vitamin C. Harvest or sprinkle it directly before eating.

Supermarket cress or homegrown on the windowsill?

The biggest difference is not the variety, but the time between harvest and plate. Vitamin C and other water-soluble vitamins degrade quickly after harvesting. If you grow your own, you know exactly when it was harvested – namely, just now.

Supermarket Cress Homegrown
When was it harvested? Unknown, often 3–7 days ago Immediately before eating
Nutrients Reduced due to storage Maximum freshness
Packaging Plastic tray None
Long-term Cost Higher with regular purchases Cheaper per serving
Control None You know exactly what you're eating

Growing garden cress on the windowsill: It's that simple

Garden cress is one of the easiest plants to grow at home. No garden, no soil, no experience needed.

What you need:

  • A microgreen pad or a shallow tray

  • Water and a bright windowsill

Here's how, step by step:

  1. Moisten the pad or tray evenly
  2. Distribute seeds evenly
  3. Water lightly daily, not too much
  4. Harvest after 5 to 7 days: simply cut above the pad and eat directly
