If you grow kale in your garden, you’ve probably seen it send up tall stalks with small yellow flowers. This often happens when the weather warms up. You might be wondering, can you eat kale flowers? The answer is a resounding yes. Not only are they edible, but these little blooms are also a nutritious and tasty part of the plant that many gardeners overlook.
When kale bolts, or goes to seed, its leaves can become bitter. But the flowers offer a sweet, mild flavor similar to broccoli or the kale leaves themselves, but with a pleasant crunch. They’re a wonderful sign that your garden is moving into a new phase, and they provide a unique harvest. Let’s look at why you should consider adding them to your plate.
Can You Eat Kale Flowers
Kale flowers are completely safe to eat. They are the natural progression of the kale plant’s life cycle. All parts of the kale plant are edible, from the roots to the leaves, stems, and flowers. The flowers are simply the next edible stage after the plant decides its leaf-producing days are done.
They are a common feature in many gardens, especially in late spring or early summer. Instead of pulling out your bolting kale, you can enjoy a secondary crop. The flowers attract beneficial insects too, which helps your entire garden thrive.
The Nutritional Benefits of Kale Blooms
Kale is famous as a superfood, and its flowers carry on that tradition. They pack a concentrated dose of the good stuff found in the leaves.
- Vitamins: They are rich in vitamins A, C, and K. Vitamin C content can be especially high in the fresh blooms.
- Antioxidants: Like other brassica vegetables, the flowers contain antioxidants like quercetin and kaempferol. These help combat oxidative stress in your body.
- Fiber: They provide dietary fiber, which supports digestive health.
- Minerals: You’ll get a boost of minerals like calcium, potassium, and iron.
Eating the flowers is a great way to reduce food waste and get the most from your garden. It’s a zero-mile food source at its peak freshness.
How Do Kale Flowers Taste?
The flavor is often a pleasant surprise. While bolting kale leaves turn bitter, the flowers tend to be milder and sweeter.
- The taste is a cross between broccoli florets and fresh kale.
- They have a slight peppery note, similar to arugula but more subtle.
- The texture is crisp and tender, especially when the flower buds are still tight.
- As the flowers fully open, the taste remains good, but the texture can become a bit more fibrous.
This makes them incredibly versatile in the kitchen. You can use them in many of the same ways you use other edible flowers or microgreens.
Identifying and Harvesting Kale Flowers
Harvesting kale flowers is simple. First, you need to correctly identify them. The flower stalks shoot up from the center of the plant. They are tall, often several feet high, with small buds and flowers clustered along the top.
The flowers are typically yellow, but some varieties may have white or pale orange blooms. The most common kale types, like curly kale and Lacinato (dinosaur kale), produce yellow flowers.
Best Time to Pick Them
For the best flavor and texture, timing is key. Harvest the flower stalks when the buds are still mostly closed or just beginning to open. At this stage, they are most tender. If you wait until all flowers are fully open, they can become a bit tougher and may start to form seed pods.
How to Harvest
- Use clean garden shears or sharp scissors.
- Cut the flower stalk a few inches below the lowest cluster of buds or blooms.
- You can harvest individual clusters if you prefer, but cutting the whole stalk is often easier.
- Place them in a container or basket to avoid bruising.
Always give them a gentle rinse in cool water to remove any dust or tiny insects before eating. Pat them dry with a clean towel or use a salad spinner.
Simple Ways to Use Kale Flowers in Your Kitchen
You don’t need to be a fancy chef to enjoy kale flowers. Their uses are straightforward and add a nice touch to everyday meals.
- Raw in Salads: Scatter the whole small clusters or individual florets over a green salad. They add color, texture, and a mild brassica flavor.
- Garnish: Use them as a beautiful, edible garnish for soups, grain bowls, or roasted vegetable plates. They make any dish look more special.
- Stir-fries and Sautés: Add them in the last minute or two of cooking. They cook very quickly and will wilt slightly, retaining a slight crunch.
- Pasta and Pizza: Toss them into pasta right before serving, or sprinkle them over a pizza after it comes out of the oven.
- Blended into Pesto: You can add a handful of the flowers to your standard basil pesto recipe for an extra nutritional kick and a slightly different flavor.
- Quick Pickle: Pickle the flower stalks or clusters in a simple vinegar brine for a tangy, crunchy condiment.
Avoid overcooking them, as they can become mushy. A light touch is best to preserve their delicate structure.
What About the Stalks and Leaves?
The flower stalk itself is also edible, especially when young and tender. If it snaps easily, it’s good to eat. You can chop it up and use it like broccoli stem—add it to stir-fries or soups where it has time to soften.
The leaves on a bolting kale plant are still edible, but their taste changes. They often become more tough and bitter. You can still use them if you don’t mind the stronger flavor. Cooking methods like sautéing with garlic or adding to a long-simmered soup can help mellow the bitterness.
Encouraging or Preventing Flowering
Sometimes you want the flowers, sometimes you don’t. If you want to keep harvesting sweet kale leaves for as long as possible, you need to delay bolting.
- Plant at the Right Time: For a spring crop, plant kale so it matures in cool weather. For a fall harvest, plant in mid-to-late summer.
- Provide Consistent Water: Drought stress can trigger early bolting.
- Use Mulch: Mulch helps keep soil temperature cool and moisture consistent.
- Choose Slow-Bolt Varieties: Some kale types are bred specifically to resist bolting in warmer weather.
If you want to harvest flowers and eventually seeds, let some of your plants follow their natural cycle. The flowers will appear as days lengthen and temperatures rise.
Saving Seeds from Your Kale Flowers
If you let the flowers mature fully, they will form long, thin seed pods. Once these pods turn dry and brown, you can collect them for next season’s planting.
- Let the flower stalks dry completely on the plant.
- Cut the dry stalks and place them in a paper bag.
- Shake the bag vigorously to release the seeds from the pods.
- Separate the seeds from the chaff and store them in a cool, dry place.
This completes the full cycle of growing your own food, from seed to seed.
Common Questions About Eating Kale Flowers
Are all kale flowers edible?
Yes, all kale flowers from edible kale varieties are safe to eat. This includes curly kale, Lacinato, Red Russian, and ornamental kale (though ornamental kale is often grown for looks, it is still edible).
Can you eat the flowers from bolting broccoli?
Absolutely. The principle is the same for broccoli, cauliflower, and other brassicas. Their flowers are edible and tasty too. Broccoli flowers are very similar to kale flowers.
Do kale flowers cause any digestive issues?
For most people, no. They are as digestible as kale leaves. If you have a sensitive stomach to cruciferous vegetables, start with a small amount to see how you feel. Cooking them lightly may make them even easier to digest for some.
How long do harvested kale flowers last?
They are best used fresh, within a day or two of harvesting. Store them in the refrigerator in a container lined with a slightly damp paper towel. Avoid washing them until just before you use them to prevent wilting.
What parts of the kale plant should you not eat?
There are no poisonous parts on a standard kale plant. However, the older, woody stems at the very base of a mature plant can be too tough and fibrous to enjoy. It’s best to compost those.
Next time your kale starts to bolt, don’t see it as the end of your harvest. See it as the beginning of a new one. Those cheerful yellow flowers are a bonus crop, offering a different flavor and a beautiful way to garnish your meals. They connect you to the full rhythm of your garden’s life. Give them a try—you might find they become a seasonal treat you look forward to each year.
