Yes, White Borage Flowers are Edible
Both the blue and white varieties of borage ($Borago officinalis$) produce flowers that are safe for human consumption when properly identified and used in moderation. The white-flowered cultivar, often sold as 'Alba' or 'Bianca', has a history of use in both culinary and medicinal contexts, just like the more common blue-flowered type. Gardeners and chefs use these flowers to add a delicate flavor and a sophisticated, decorative touch to a wide range of dishes and drinks.
The Refreshing Taste and Texture
White borage flowers, similar to their blue counterparts, are prized for their unique, mild flavor profile.
- Flavor: The taste is often described as a fresh, clean cucumber flavor with a slightly sweet or honey-like finish. Some people have even noted an intriguing resemblance to the taste of raw oysters.
- Texture: The texture of the fresh petals is slightly succulent and chewy, offering a pleasant contrast in salads or on top of desserts. The stems and leaves, while edible, are covered in fine hairs that can be unpalatable for some and should be cooked or used when young.
Culinary Uses for White Borage Flowers
White borage flowers are versatile and can elevate both sweet and savory recipes. Their pristine color makes them an excellent garnish that complements many dishes where a touch of floral elegance is desired.
Innovative Culinary Applications
- Elegant Garnishes: Sprinkle fresh white borage flowers over salads, soups, or cold dishes to add a pop of subtle flavor and visual appeal.
- Summer Beverages: Freeze the flowers in ice cubes to create stunning, decorative additions to summer drinks like lemonade, iced tea, and cocktails.
- Dessert Decoration: Use fresh or candied flowers to decorate cakes, cookies, and pastries. Crystallized borage flowers make for a beautiful and long-lasting garnish.
- Infusions: Add fresh flowers to cold water, white wine sangria, or vinegars for a refreshing infusion.
- Pasta and Fritters: In some traditional Italian regions like Liguria, borage flowers and leaves are used to stuff pasta like ravioli or are incorporated into savory fritters.
Important Safety Considerations
While white borage flowers are generally safe to consume, there are important safety guidelines to follow. The plant contains low levels of naturally occurring pyrrolizidine alkaloids (PAs), which can be toxic to the liver in high or concentrated doses.
Comparison: Borage Flowers vs. Borage Leaves
To highlight the nuances of consuming different parts of the plant, here is a comparison:
| Feature | Borage Flowers | Borage Leaves | Borage Seed Oil | 
|---|---|---|---|
| Edibility | Safe in moderation | Edible, but mature leaves are hairy | Can have liver toxicity unless certified PA-free | 
| Best Uses | Garnish, drinks, desserts | Soups, cooked greens, tea | Health supplements (PA-free only) | 
| PA Content | Very low levels | Contains low levels | Contains PAs unless processed | 
| Taste | Mild cucumber, honey, or oyster | Mild cucumber | Varies; not used for flavor | 
| Primary Risk | None in moderation | Small risk with chronic, high intake | Potential liver damage if not certified | 
Best Practices for Safe Consumption
- Moderation is Key: Consume borage flowers and young leaves sparingly. It is not recommended for daily, long-term consumption.
- Consult a Professional: Pregnant or breastfeeding women, individuals with liver disease, and those on blood thinners should avoid consuming borage. Always consult a healthcare provider for personalized advice.
- Ensure Purity: Only consume flowers from a trusted source, such as your own organic garden, to ensure they are free of pesticides and other chemicals. Do not use flowers from a florist or garden center.
- Proper Harvesting: Pick flowers in the morning after the dew has dried for the best freshness. Gently wash them by dipping in a bowl of cool water to avoid damaging the delicate petals.
How to Grow and Harvest White Borage
White borage ($Borago officinalis$ 'Alba') is an easy-to-grow annual herb that self-seeds readily, making it a low-maintenance addition to any garden.
Cultivating Your Own
To ensure a fresh and safe supply of edible flowers, growing your own is the best option.
- Sow Seeds Directly: Borage has a long taproot and does not transplant well. Sow seeds directly into a sunny spot with well-drained soil after the last frost.
- Attract Pollinators: Borage is a potent bee magnet and a great companion plant for other vegetables like tomatoes and squash.
- Encourage Growth: Fertilize plants in poor soil with an organic fertilizer rich in phosphorus. Water well, especially during dry periods.
- Manage Self-Seeding: If you want to control its spread, deadhead the flowers before they go to seed.
Harvesting Tips
- Time of Day: Harvest flowers in the morning for peak freshness.
- Cleaning: Dip flowers in a bowl of cool water and pat dry gently on a paper towel.
- Storage: Use fresh borage flowers as soon as possible. They can be stored in an airtight container in the refrigerator for a few days.
