There’s something satisfying about pulling a flower from your own garden and putting it directly on a cake or in a recipe. No guessing where it came from, no wondering about pesticides, just something you grew yourself making it onto something you baked.
Edible flowers aren’t a new trend. People have been baking with them for centuries. The Romans pressed petals like violet (pansies) and dianthus into honey cakes, and by the Victorian era crystallized flowers had become the signature decoration on high-society wedding cakes. They feel out of fashion for a while when commercial bakeries leaned into synthetic dyes and sugar flowers, but the recent wave of naked cakes and rustic, garden-style baking has brought real petals right back onto buttercream.
This post is mostly rooted in what I grow myself, with a few extras worth knowing about at the end. Before we get into it though, a quick but important note: Not every flower is food-safe, and even the edible ones should be sourced carefully. Avoid anything sprayed with pesticides or treated with chemicals, like flowers from a commercial florist, and if you’re buying rather than growing your own, look for plants grown organically, labeled food-safe or sold specifically for culinary use.

Edible Flowers
Pansies and Violas
Pansies and violas are one of the most recognizable and probably my favorite edible flower for cake decorating. They have a naturally flat face that is almost intentionally designed for pressing onto frosting, which makes them ideal for drying, candying, or using fresh. I like to use them fresh, placed directly onto buttercream.
The flavor is mild and subtle enough that it doesn’t compete with whatever the cake. I recently used pansies on my Grandma’s Sponge Cupcake paired with a mascarpone Chantilly, and I didn’t notice the taste of the flowers at all.
Fun fact: pansies have been eaten since the days of the ancient Greeks and Romans, who used them in garlands and wine infusions. By the Victorian era is when they became the quintessential dessert flower, and they’re still the most famous choice for sugar-candying and pressing onto cakes. (and rightfully so!)
Nasturtium
Nasturtiums are supposably one of the easiest edible flowers to grow and one of the most useful in the kitchen. Both the flowers and the leaves are edible, with a peppery, slightly spicy flavor.
From what I have seen, they mainly come in warm colors; beige, yellow, orange, red, peach. The variety I am growing are called “bloody Mary” and they have a mix of these colors and some variegation. For decorating, the bright oranges, reds, and yellows look great against neutral or white frosting. The petals are a bit more delicate than pansies, so they work best placed just before serving.
Fun fact: nasturtiums were mainly grown for Victorian bouquets until the British realized the whole plant was edible. These days they are typically used as a garnish or scattered over desserts.
Lavender
Lavender is one of those ingredients where a little goes a long way, and too much goes from floral to soapy fast. But used in smaller amounts, it’s one of the most elegant flavors in baking.
For decorating, dried lavender sprigs add a beautiful textural element to a cake and the color is a natural fit for a lot of buttercream palettes. In recipes, lavender simple syrup is probably the most versatile application: it works in cake soaks, frostings, and glazes. Lavender pairs especially well with lemon, honey, and vanilla.
Fun fact: lavender didn’t start out as a culinary herb at all. Its name comes from the Latin lavare, meaning to wash, a hint at what it was originally used for. It wasn’t until medieval Europe that it was dried to flavor royal stews, teas, and conserves, and today it’s a favorite for infusing into cake soaks, syrups, and frostings.
Sweet Alyssum
Sweet alyssum is one of those underrated edible flowers that doesn’t get talked about as much as it should. The tiny clustered blooms have a faint honey-like fragrance. For decorating, gently press the fresh blooms directly into buttercream, or use edible glue to attach them to fondant. You can also buy pre-pressed alyssum or dry your own to create soft floral arrangements on the sides of cakes.
Fun fact: sweet alyssum is native to the Mediterranean, where it was originally grown as a medicinal herb rather than anything you’d put on a dessert. On cakes it works almost like edible confetti, adding a soft, fairy-like texture.
Cosmos
Cosmos make a wonderful decorating flower. The shape is simple and clean, with petals that radiate out from a bright center, and the color range from white to deep magenta is genuinely amazing.
I’m growing cosmos this year specifically as reference for buttercream flowers, though you can also decorate with the real thing, fresh or dried whole or pressed flat.
Fun fact: the name cosmos comes from the Greek word for order and harmony, a nod to the flower’s evenly spaced, perfectly symmetrical petals. That clean, flat geometry is exactly why it’s become such a favorite for modern decorating, especially pressed flat against buttercream for rustic, garden-style cakes.
Dahlia
You may be surprised to know that dahlia petals are edible. For decorating, the layered structure of a full bloom is intricate and the color range is as wide as any flower gets. Because the bloom is so geometric, you can either pull the petals apart and scatter them like feathers over a cake, or use a whole head as a dramatic statement on top. You can use them fresh, dried, or candied.
I’m growing Edinburgh this year, a deep purple to white-edged decorative variety, and that layered shape is exactly the kind of thing I love recreating in buttercream.
Fun fact: dahlias were originally cultivated by the Aztecs as a food crop. They ate the starchy tubers like potatoes and used the hollow stems to carry water. When the plant reached Europe in the late 18th century the roots never caught on as a vegetable, but the petals quickly found their way into the culinary world.
Dianthus
Surprisingly, and new to me, dianthus petals are also food-safe and entirely edible. They have a mild, slightly sweet and clove-like flavor, though they are more used as a garnish than as an ingredient in modern culinary spaces. But fun fact they’ve been used as edible flowers dating back to roman times and traditional French liqueur making.
Fun fact: the Greeks and Romans used dianthus petals to flavor their wines and oils, and people have been eating them ever since. Their frilled, fringed edges, are part of what makes them such a pretty cake flower today, whether candied or used fresh.
Other Edible Flowers Worth Knowing
A few others that come up often in baking and decorating, even if they’re not in my garden this year:
Roses: both petals and rose water are widely used in baking, especially in cakes, syrups, and Middle Eastern desserts.
Elderflower: a classic choice for syrups and cordials, with a delicate floral flavor that pairs especially well with citrus.
Chamomile: mild and apple-like in flavor, chamomile works beautifully infused into simple syrups, creams, and cakes.
Lilacs: lightly floral and fragrant, they can be infused into syrups, sugar, and frostings.
Borage: a bright blue star-shaped flower with a mild cucumber-like flavor that works well candied or used fresh as a garnish.
A Few Harvest Tips
Since the whole point here is growing your own, a few notes on prepping what you pick:
Harvest in the morning. Clip your blooms early in the day, once the dew has dried but before the hot sun gets to them. That’s when they’re freshest and least likely to wilt.
Give them a gentle wash. Float the flowers in a bowl of cool water and give them a soft shake to dislodge any little garden bugs hiding in the petals, then lay them flat on a paper towel to dry before they go anywhere near frosting.
Snip the bitter bits. The base of a petal can be bitter on some flowers, like dianthus and roses, so it’s worth pinching that part off before you use them.
Final Notes
Most of these flowers ended up in my garden as inspiration for buttercream flowers and cake designs, but it’s been fun discovering another side to them too. Some work beautifully pressed onto cakes, some can be infused into baking, and all of them add a little more connection between the garden and the kitchen.
It’s also a small way of carrying on a really old tradition. People have been decorating cakes with real flowers for centuries, and while decorating styles have shifted over time, fresh flowers have never really disappeared. It’s interesting seeing them continue to evolve, from Victorian crystallized petals to the natural, garden-inspired cake designs that have become so popular in recent years.
If you’re just getting started with edible flowers, pansies and nasturtiums are probably the easiest place to begin. They’re easy to grow, widely available, and genuinely useful whether you’re decorating cakes or experimenting with baking.
One last reminder: not every flower is food-safe, and even edible flowers should be sourced carefully. Florist flowers are often treated with pesticides and other chemicals, so it’s best to stick with blooms from a reputable food-safe source of grow your own organically and wash them well before using them.
I’ll be sharing more as things bloom this summer, and if you want to follow along in real time, I share garden and flower photos regularly on Pinterest.
