Beautiful & Safe: Flowers You Can Use on Wedding Cakes

---

At Wildflour Kitchen, we believe your wedding cake should taste just as incredible as it looks—and that includes every last detail, right down to the flowers. Whether you’re going for whimsical, romantic, rustic, or modern, fresh flowers are one of the most elegant and timeless ways to elevate your cake. But not all blooms are created equal. Some are safe, while others are toxic and should never touch food.

So, which flowers can you safely use on your wedding cake? Here’s a list of edible and non-toxic blooms that are as beautiful as they are bakery-friendly.

Florals Commonly Used on Cakes

• Roses – Soft petals with a subtle, sweet flavor. Great for romantic themes.
• Pansies – Bright and cheerful; come in many colors with a mild grassy flavor.
• Violas – Smaller cousins of pansies, perfect for fine detail work.
• Lavender – Fragrant and floral; use sparingly due to strong flavor.
• Nasturtiums – Peppery and vibrant; often used in salads and savory bakes.
• Calendula (Marigold) – Sometimes called “poor man’s saffron.” Petals are colorful and slightly tangy.
• Chamomile – Delicate daisy-like flowers with a sweet, apple-like flavor.
• Cornflowers (Bachelor’s Button) – Mild clove-like taste and brilliant blue color.
• Borage – Cucumber-flavored flowers, usually blue or purple.
• Hibiscus – Tart and cranberry-like; often used in teas and syrups.
• Violets – Sweet and floral; great for sugaring and garnishing.
• Begonias (tuberous) – Tangy, citrus-like flavor. Only certain varieties are edible.
• Sunflowers (petals only) – Slightly nutty. Use young, tender petals.
• Dianthus (Pinks) – Clove-like taste. Remove the bitter white base of petals.
• Snapdragons – Edible but slightly bitter; used more for appearance.
• Gladiolus – Flavorless, but safe. Use petals to line tiers or fill with creams.
• Fuchsias – Tart and decorative, often used for a pop of color.
• Impatiens – Mild flavor and wide color range.

• Mint Blossoms – Delicate and minty; great on chocolate cakes or drinks.
• Cilantro Blossoms – Herbaceous and citrusy, great for savory bakes.

Important Guidelines

• Always source organically grown, pesticide-free flowers. Never use flowers from florists, garden centers, or roadsides unless you’re sure they’re untreated.
• Wash gently and dry flowers before use.
• Use in moderation—some edible flowers can have intense flavors or may affect those with allergies.
• Avoid the stems, stamens, and pistils unless specifically noted as safe—usually only the petals are eaten.

These flowers are not poisonous, but they’re not intended for consumption either. They’re considered food-safe when used correctly—typically wrapped or inserted with floral picks/straws to prevent sap or moisture from touching the cake.

Commonly Used Non-Edible, Non-Toxic Wedding Flowers:

• Peonies
  Soft, romantic, and a wedding favorite. Non-toxic but not edible.
• Ranunculus
  Delicate and full-petaled blooms in many colors. Safe to use decoratively.
• Snapdragons
  Tall and structured, these flowers add vertical interest to floral arrangements on cakes.
• Lisianthus
  Elegant and soft-colored, often mistaken for roses. Non-toxic, but not for eating.
• Zinnias
  Bright and cheerful flowers that work well on rustic or summer cakes.
• Gerbera Daisies
  Bold and colorful—non-toxic but inedible. Great for vibrant designs.
• Petunias
  Mild scent and variety of colors. Considered safe for external cake decoration.
• Cosmos
  Dainty flowers with long stems and airy appearance—harmless but not for eating.
• Camellias
  Shiny leaves and layered petals. Use with care as decor only.
• Asters
  Starry-shaped blooms in purple, pink, and white tones. Decorative, not edible.
• Corn Marigold (Glebionis segetum)
  A pretty yellow flower often confused with calendula—non-toxic but not edible.
• Bee Balm (Monarda)
  Aromatic and colorful; used in herbal teas but typically not eaten raw. Use petals only for decorative safety.

Safety Notes When Using These Flowers on Cakes

• Never insert flowers directly into the cake. Use food-safe picks, straws, or wrap stems in floral tape and plastic wrap.
• Avoid blooms that leak sap or have fuzzy/powdery pollen unless the petals are the only part used.
• Source organically and pesticide-free blooms. Avoid supermarket or florist flowers unless they’re food-safe certified.
• Do not let flowers sit too long on buttercream. Some blooms can wilt or leach moisture if left on for hours in warm environments.

• Go Organic: Always use flowers that are organic and free from pesticides or chemical treatments. Store-bought florals are often treated and should not be used on food.
• Prep with Care: Wash flowers gently, trim the stems, and use food-safe flower picks or wrap stems in floral tape and plastic wrap to prevent sap from seeping into the cake.
• Avoid Toxic Flowers: Some common wedding flowers—like hydrangeas, lilies, foxglove, and baby’s breath—are toxic and should never be used on cakes.
• Consult a Professional: At Wildflour Kitchen, we’re happy to work with your florist or supply our own safe, stunning florals to match your wedding palette and theme.
