What Are Nasturtium Flowers?
So, you’re probably curious about what exactly nasturtium flowers are and how they differ from their more common edible counterparts. Let’s explore the basics of these beautiful blooms!
Origin and History of Nasturtium Flowers
Nasturtium flowers have a rich and diverse history that spans across various continents. Originating from South America, specifically in present-day Colombia and Peru, these delicate blooms were first discovered by European botanists in the 16th century. They quickly gained popularity among gardeners for their vibrant colors, ease of growth, and unique fragrance.
In ancient times, nasturtium flowers were used for their medicinal properties, particularly to treat various skin conditions and wounds.

By choosing the right variety for your environment, you’ll be able to enjoy their nutritional benefits while also appreciating their unique beauty.
Nutritional Content of Nasturtium Flowers
Nasturtium flowers are not only a beautiful addition to your garden, but they’re also packed with nutrients that can boost your health and well-being in several ways. Let’s take a closer look at their impressive nutritional profile.
Protein and Amino Acid Content
Nasturtium flowers are not only a vibrant addition to salads and sandwiches but also a rich source of protein and essential amino acids. According to the United States Department of Agriculture (USDA), nasturtium flowers contain about 2-3 grams of protein per 100 grams of edible flower petals.
What’s more impressive is that they provide all nine essential amino acids necessary for human health, making them an excellent option for vegetarians and vegans looking to boost their protein intake.

Health Benefits of Nasturtium Flowers
You might be surprised by all the ways nasturtium flowers support our health, from fighting off infections to soothing irritated skin and eyes. Let’s explore these benefits in more detail.
Anti-Inflammatory Properties
When it comes to fighting inflammation, nature has provided us with some incredible tools. Nasturtium flowers are one of them, packed with anti-inflammatory compounds that can have a significant impact on human health.

In fact, studies have demonstrated that consuming nasturtium extracts can reduce inflammation by up to 30% in just two weeks.
But how can you harness the anti-inflammatory power of nasturtium flowers? One simple way is to incorporate them into your cooking. Nasturtium petals can be used as a garnish or added fresh to salads, soups, and sauces. You can also make nasturtium tea by infusing dried flowers in hot water. With its mild, peppery flavor, nasturtium tea makes for a delicious and healthy addition to your daily routine.
Incorporating nasturtium flowers into your diet may not only alleviate inflammation but also boost overall well-being. As with any new food or supplement, be sure to consult with a healthcare professional before making them a regular part of your routine.
Antioxidant Activity
Nasturtium flowers are packed with antioxidants that can have a significant impact on our overall well-being. Antioxidants are molecules that neutralize free radicals, which can cause oxidative stress and lead to chronic diseases such as cancer, diabetes, and heart disease.
The antioxidant activity in nasturtium flowers is primarily attributed to the presence of flavonoids, carotenoids, and phenolic acids. These compounds have been shown to exhibit anti-inflammatory properties, protect against cell damage, and even have antimicrobial effects.
One of the key antioxidants found in nasturtium flowers is beta-carotene, a precursor to vitamin A that also has potent antioxidant properties. Consuming nasturtium flowers or using them as a garnish can provide a boost of this essential nutrient, supporting healthy vision, immune function, and skin health.
To reap the antioxidant benefits of nasturtium flowers, simply add fresh petals to salads, use them as a garnish for soups, or blend them into smoothies. You can also dry the flowers and store them in an airtight container for later use. By incorporating nasturtiums into your diet, you’ll be taking a step towards protecting yourself against oxidative stress and promoting overall health.
Culinary Uses of Nasturtium Flowers
You’ll be delighted to know that nasturtium flowers are not just a pretty face, but also add a burst of flavor and color to various dishes when used as a garnish or edible flower. Let’s explore some delicious ways to use them in the kitchen.
Salads and Garnishes
When it comes to adding flavor and nutrition to your dishes, nasturtium flowers are an excellent choice. Not only do they add a pop of color, but they also pack a punch of vitamins and minerals. To use nasturtium flowers as a garnish or add them to salads, follow these simple preparation methods.
Start by gently washing the petals in cold water to remove any dirt or debris. Pat dry with paper towels to prevent excess moisture from affecting the texture. You can then chop or tear the petals into smaller pieces, depending on your desired level of texture. To use as a garnish, simply arrange the chopped flowers on top of your dish, or mix them into your salad for an added burst of flavor and nutrition.
Some popular ways to incorporate nasturtium flowers into salads include adding them to a caprese salad with fresh mozzarella and tomatoes, or using them as a topping for a grain bowl. The peppery flavor of the flowers pairs particularly well with citrus-based dressings and light vinaigrettes. When working with nasturtium flowers, remember that a little goes a long way – start with small amounts and adjust to taste. This will ensure you don’t overpower the other flavors in your dish.
Other Culinary Applications
Beyond adding flavor and nutrition to salads, nasturtium flowers can also be used in a variety of other culinary applications. One way to enjoy their unique taste is by infusing them into teas, which can be enjoyed hot or iced. To make nasturtium flower tea, simply steep the flowers in boiling water for 5-7 minutes, then strain and sweeten as desired.
You can also use nasturtium flowers to add a burst of flavor to sauces and marinades. Try adding a few petals to your favorite pasta sauce or stir-fry recipe for an instant boost of nutrition and taste. The key is to use the flowers in moderation, as their delicate flavor can quickly overpower other ingredients.
For a more subtle effect, try using nasturtium flowers as a garnish or topping for dishes like tacos, salads, or soups. Their bright colors and delicate petals add a pop of visual appeal that’s sure to impress dinner guests. Experiment with different combinations of flavors and textures to find your favorite ways to use nasturtium flowers in the kitchen.
Precautions and Potential Interactions
Before using nasturtium flowers, please note that some individuals may experience adverse effects, especially when combined with certain medications. We’ll discuss potential interactions and precautions to be aware of below.
Allergies and Sensitivities
If you’re considering adding nasturtium flowers to your diet, it’s essential to be aware of potential allergies and sensitivities. Some people may experience adverse reactions to these beautiful blooms due to their unique properties.
Symptoms can range from mild discomfort to severe reactions. Common allergic responses include skin irritation, hives, itching, and swelling. In some cases, people may also experience gastrointestinal issues such as nausea, vomiting, or diarrhea. If you notice any of these symptoms after consuming nasturtium flowers, seek medical attention immediately.
To minimize the risk of an adverse reaction, start with a small serving size and monitor your body’s response. Also, be cautious if you’re allergic to other Brassica family members like broccoli, cauliflower, or kale, as nasturtiums belong to this group.
If you experience an allergic reaction, consult a healthcare professional for proper diagnosis and treatment. They may recommend antihistamines or corticosteroids to alleviate symptoms. In severe cases, hospitalization may be necessary.
Medicinal Interactions

For example, if you’re taking blood thinners such as warfarin or aspirin, consuming nasturtium flowers in large quantities may increase the risk of bleeding. This is because vitamin K, found in nasturtiums, can counteract the anticoagulant properties of these medications. Similarly, individuals with high blood pressure should be cautious when consuming nasturtiums, as their potassium content may interact with blood pressure medications like beta blockers.
To minimize potential interactions, it’s crucial to inform your healthcare provider about any herbal supplements or flower extracts you plan to consume. If you’re taking prescription medication, start by introducing small amounts of nasturtium flowers into your diet and monitor your body’s response closely. Some individuals may experience adverse effects when combining nasturtiums with certain medications, so be sure to prioritize caution and consult with a healthcare professional if you have any concerns.
Growing and Harvesting Nasturtium Flowers for Nutrition
Nasturtium flowers can be harvested at various stages of growth, from young buds to fully open blooms, making them a versatile addition to salads and dishes. Here’s how to grow and harvest these nutritious flowers for maximum flavor and nutrition.
Tips for Cultivating Healthy Plants
To maximize the nutritional potential of nasturtium flowers, it’s essential to cultivate healthy plants. This starts with selecting a sunny location with well-draining soil that’s rich in organic matter. Nasturtiums prefer slightly acidic to neutral soil pH, between 6.0 and 7.0.
When planting, ensure the seeds are about 1-2 inches deep and spaced 6-12 inches apart. Water gently but thoroughly after sowing, and maintain consistent moisture levels throughout their growth cycle. Avoid overwatering, which can lead to root rot and other issues.
Fertilization is also crucial for optimal nutrition. Feed your nasturtiums with a balanced fertilizer (10-10-10 NPK) once a month, following the manufacturer’s instructions. Additionally, consider incorporating compost tea or worm castings into your soil to boost nutrient levels.
Regular pruning encourages bushy growth and prevents sprawling. Pinch off flower buds as they form, allowing the plant to focus energy on leaf development. This ensures you reap the most benefits from your nasturtium harvest, including their high water content and rich supply of vitamins A, C, and K.
Timing and Methods for Harvesting
Harvesting nasturtium flowers at the right time is crucial to ensure optimal nutrition. The best time for harvesting depends on the color and purpose of the flowers. For edible arrangements and salads, harvest bright yellow, orange, or red flowers when they’re fully open, as they’ll retain their vibrant colors and flavor. For uses like making nasturtium tea, pick slightly less mature flowers with a more delicate appearance.
To maximize nutritional value, it’s essential to harvest nasturtium flowers in the morning after the dew has evaporated but before the sun becomes too intense. This ensures that the water content is minimal, which can lead to spoilage and loss of nutrients. Harvest individual blooms by cutting them off at the base with scissors or pinch them off with your fingers.
For optimal nutrition, consider harvesting a mix of flowers in various stages of maturity. Younger, more delicate flowers are rich in vitamin C and antioxidants, while older flowers contain more beta-carotene and other carotenoids. Experiment with different harvesting times to find what works best for you and your intended uses.

While they may not be as widely known as other edible flowers, they offer a range of health benefits and can be easily incorporated into your diet. By adding them to salads, soups, or using them as a garnish for various dishes, you can reap the rewards of their vitamin C content, anti-inflammatory properties, and rich antioxidants. To make the most of nasturtium flowers’ nutritional information, remember to use them fresh and in moderation, as excessive consumption may cause stomach upset. Experiment with different recipes and cooking methods to find your favorite ways to enjoy these delicious and nutritious flowers.
