My Top 7 Picks for a Blooming Edible Pantry
Over the years, I've experimented with countless varieties of edible flowers, searching for those that not only taste wonderful but also thrive reliably in my greenhouse environment. My criteria are simple: they must be relatively easy to grow, offer consistent blooms, and provide a delightful sensory experience—both visually and culinarily. It's about finding that perfect balance of beauty and utility. From the peppery kick of nasturtiums to the delicate sweetness of pansies, each of these flowers brings something unique to my kitchen and garden. I love how they transform an ordinary dish into something extraordinary, adding layers of flavor and a touch of whimsy that never fails to impress. Here are the seven stars of my edible flower garden, the ones I simply can't live without: - **Nasturtiums**: Known for their vibrant colors and peppery flavor, reminiscent of watercress.
- **Pansies & Violas**: Delicate, sweet, and visually stunning, perfect for desserts and salads.
- **Borage**: Offers a subtle cucumber flavor with beautiful star-shaped blue flowers.
- **Calendula**: A cheerful bloom with a slightly tangy, peppery taste, often used as a saffron substitute.
- **Edible Roses**: Classic elegance with a fragrant, mildly sweet flavor, especially from specific varieties.
- **Lavender**: Aromatic and calming, with a strong floral flavor that's best used sparingly.
- **Chive Blossoms**: Delicate purple spheres with a mild oniony, garlicky flavor, adding a gourmet touch.
Nasturtiums: A Peppery Splash of Color
Nasturtiums are, without a doubt, one of my absolute favorites for greenhouse cultivation. Their vibrant, jewel-toned flowers and lily pad-shaped leaves bring such a cheerful energy to my space, and their peppery flavor is incredibly versatile. I grow both trailing and bush varieties, allowing them to spill out of pots or create a dense ground cover in my raised beds. They are remarkably unfussy, thriving in full sun and well-drained soil, and they seem to just keep on giving. Harvesting nasturtiums is a breeze; I simply snip the flowers and leaves as needed, making sure to pick them in the morning after the dew has dried. The more I harvest, the more they tend to produce, which is a gardener’s dream! I always ensure to only pick from plants I know haven't been treated with any pesticides, as safety is paramount when consuming anything from the garden. In the kitchen, nasturtiums are a delight. I love tossing the leaves and flowers into a green salad for a spicy kick, or using the blossoms as a vibrant garnish for soups and entrées. The unripened seed pods can even be pickled, creating a fantastic caper substitute. For a simple appetizer, I often stuff the flowers with a creamy herbed cheese spread, offering a burst of flavor and color that always impresses guests.
Pansies & Violas: Delicate Charm, Sweet Flavor
Pansies and violas are the unsung heroes of my edible flower collection. While often overlooked for their culinary potential, their delicate, slightly sweet flavor and incredible range of colors make them perfect for adding an elegant touch to almost any dish. In my greenhouse, they provide consistent blooms even during cooler months, bringing a much-needed splash of cheer when the outdoor garden is dormant. I find they do best in slightly cooler parts of the greenhouse, away from direct, intense midday sun, ensuring their petals remain vibrant and unspoiled. I harvest pansies and violas by gently snipping the flowers at the base of their stem, usually in the early morning. It's important to be delicate, as their petals are quite fragile. I store them carefully on a damp paper towel in a sealed container in the refrigerator, which helps them stay fresh for a few days. Always remember to remove the small green calyx at the base of the flower before consuming. My favorite ways to use these charming blooms include garnishing cakes and cupcakes, floating them in a sparkling drink, or scattering them over fruit salads for a burst of color and subtle sweetness. They also make a beautiful addition to a cheese board, offering a visual delight that complements savory flavors without overpowering them. Sometimes, I even press them between wax paper and use them to decorate homemade shortbread cookies for a truly elegant treat.
Borage: A Taste of Cucumber Freshness
Borage is a truly unique addition to my edible flower garden, primarily for its distinctive, refreshing cucumber-like flavor. Its vivid blue, star-shaped flowers are not only beautiful but also incredibly easy to grow and maintain in the greenhouse. I've found that borage thrives with consistent moisture and plenty of sunlight, growing into bushy plants that produce a continuous supply of blooms. It's an annual, but it readily self-seeds, so I often find new plants popping up, ensuring a steady harvest. To harvest borage flowers, I simply pinch them off at the base of the bloom. It's best to pick them fresh, just before use, as they are quite delicate and don't store as well as some other edible flowers. I always check for any small hairs on the leaves and stems; while the flowers are generally hair-free, the leaves can be slightly prickly for some, so I tend to focus on the petals themselves for culinary use. I love using borage to add a fresh, cool note to my summer drinks, especially lemonade or Pimm's Cup, where they float like little blue stars. They're also fantastic scattered over a fresh green salad or used to garnish a chilled cucumber soup. For a refreshing twist, I sometimes freeze them into ice cubes with a sprig of mint, creating beautiful and flavorful additions to any beverage. The flavor is mild enough that it won't overwhelm, but distinct enough to be noticed.
Calendula: Cheerful Blooms with a Tangy Twist
Calendula, often known as 'pot marigold,' is a sun-kissed favorite in my greenhouse. Its cheerful yellow and orange petals bring such warmth and vibrancy, making it a joy to behold, even on the grayest days. Beyond their beauty, calendula flowers offer a slightly tangy, subtly peppery flavor that I find incredibly interesting in culinary applications. They are robust growers, flourishing in full sun and well-drained soil, and consistent deadheading encourages a prolific bloom cycle all year long under greenhouse protection. Harvesting calendula is as simple as gently plucking the petals from the flower head, or if I want the whole flower for garnish, I snip the stem just below the bloom. It’s best to harvest when the flowers are fully open but still fresh, typically in the late morning after any dew has evaporated. I lay them on a clean tray to air dry for a short period if I plan to store them, or use them immediately to capture their freshest flavor. I often use calendula petals to add a pop of color to rice dishes, where they can also impart a subtle golden hue, much like saffron. They're wonderful tossed into egg dishes like omelets or scrambles, and their flavor pairs beautifully with creamy pasta sauces. For a refreshing beverage, I sometimes infuse calendula petals into honey for a delicate floral sweetener, or simply sprinkle them over a vibrant green salad for visual appeal and a unique flavor note. They truly bring sunshine to my plate.
Roses: Classic Elegance for the Edible Garden
When I mention edible flowers, many people immediately think of roses, and for good reason! Their timeless beauty and intoxicating fragrance make them a natural choice for culinary use. In my greenhouse, I cultivate specific rose varieties that are known for their strong scent and flavor, ensuring they are free from any chemical treatments. Miniature roses or specific old garden roses tend to do particularly well in pots, which allows me to control their environment more precisely and bring them inside my greenhouse for year-round protection and blooming. Harvesting rose petals requires a gentle touch. I select fully open, fragrant blooms and carefully pluck the individual petals, discarding any that show signs of damage or discoloration. The best time to harvest is in the early morning, just after the dew has dried, when their essential oils are most concentrated. It's crucial to remove the white heel at the base of each petal, as it can be bitter. I gently rinse the petals and lay them out to air dry on a clean cloth before use. Rose petals add a sophisticated touch to a variety of dishes. I love making rosewater for use in Middle Eastern-inspired desserts, or simply sprinkling fresh petals over fruit tarts, ice cream, or rice pudding. They also make a beautiful and fragrant addition to a champagne cocktail or a delicate herbal tea. For a truly luxurious treat, I crystalize the petals with egg white and sugar, creating stunning, edible decorations for special occasions.
Lavender: Aromatic Bliss for Sweet & Savory
Lavender holds a special place in my greenhouse for its unmistakable aroma and beautiful purple spikes. While its flavor is potent and should be used judiciously, it brings such a sophisticated, calming note to both sweet and savory dishes. I grow English lavender varieties in large pots within my greenhouse, as they tend to be more compact and their flavor is generally preferred for culinary purposes over other types. They thrive in bright light and well-drained soil, making the greenhouse an ideal environment to ensure year-round availability. When harvesting culinary lavender, I look for fresh, unopened buds or newly opened flowers, as these contain the most concentrated flavor and aroma. I snip the flower stems at the base, typically in the morning. After harvesting, I gently remove the tiny florets from the stems. It's important to use them fresh or dry them thoroughly for later use, ensuring they are free from moisture to prevent mold. A little goes a long way with lavender, so I always start with a small amount and taste as I go. My favorite uses for lavender include infusing simple syrups for cocktails or lemonades, creating delicate lavender shortbread cookies, or adding a pinch to a dry rub for roast chicken or lamb. I’ve also had great success making lavender sugar, which is lovely sprinkled over fresh berries or used in baking. For a truly relaxing experience, a small sachet of dried lavender from my greenhouse sits beside my bed.
Chive Blossoms: The Onion's Elegant Crown
Chive blossoms are perhaps one of the most delightful edible flowers I cultivate in my greenhouse, offering a mild, delicate oniony flavor in a beautiful, spherical package. My chive plants thrive year-round in pots, offering not only their edible leaves but also these charming purple flowers. The greenhouse environment allows them to produce continuous blooms, even when my outdoor chives are dormant. They are remarkably low-maintenance, requiring only adequate light and consistent watering to flourish. Harvesting chive blossoms is incredibly easy: I simply snip the flower head at the base of its stem. I like to harvest them when they are fully formed but before they start to fade, usually in the mid-morning. It's best to use them fresh, as their delicate flavor and texture are at their peak. I always give them a gentle rinse under cool water and pat them dry before adding them to any dish. These beautiful purple orbs are perfect for adding a gourmet touch to almost anything savory. I love scattering them over scrambled eggs, baked potatoes, or a fresh green salad. They also make a stunning garnish for cream cheese spreads, dips, or even a simple bowl of soup. Sometimes, I gently separate the individual florets and sprinkle them over a cheese board or use them to decorate a savory tart, offering a subtle hint of onion without the pungency of raw chives. They truly elevate a dish with minimal effort.
Cultivating Success: My Essential Greenhouse Tips
Growing edible flowers in a greenhouse, while rewarding, does require a bit of attention to detail to ensure they thrive year-round. It's not just about planting them; it’s about creating the optimal environment that mimics their ideal outdoor conditions, but with added protection and control. I've learned that consistency in care is key, as is understanding the specific needs of each plant. My primary focus is always on providing ample light, proper ventilation, and precise watering. Overwatering is a common pitfall, so I always check the soil moisture before reaching for the watering can. I also pay close attention to pest management, preferring organic methods to ensure my flowers remain safe for consumption. Creating this balanced ecosystem ensures a continuous harvest of beautiful, flavorful blooms. Here are some of my go-to practices for keeping my edible flowers happy and healthy: - **Consistent Air Circulation**: Install fans to prevent stagnant air, which can lead to fungal diseases and helps regulate temperature. This is crucial for healthy growth.
- **Optimized Lighting**: Supplement natural light with grow lights during shorter winter days, ensuring your plants receive 12-14 hours of light daily for continuous blooming.
- **Soil Quality is Key**: Use a high-quality, well-draining potting mix. For plants in containers, I refresh the soil annually and provide balanced organic liquid fertilizer monthly during active growth.
- **Integrated Pest Management (IPM)**: Regularly inspect plants for pests. I prefer using beneficial insects like ladybugs or introducing organic pest sprays like neem oil as a first line of defense.
- **Mindful Watering**: Water deeply but infrequently, allowing the top inch of soil to dry out between waterings. Use a moisture meter if unsure. Good drainage is paramount.
- **Harvest Regularly**: Consistent harvesting encourages more blooms. Think of it as pruning; it tells the plant to produce more flowers and keeps them from going to seed too quickly.
- **Temperature and Humidity Control**: Monitor your greenhouse's temperature and humidity levels. Many edible flowers prefer moderate temperatures (60-75°F or 15-24°C) and average humidity. Use vents and misters as needed.
