Cornflower Specifications & Characteristics
Available in both certified organic and conventional qualities to suit your formulation needs.
What is Cornflower?
Cornflower (Centaurea cyanus) is a slim, upright wildflower native to temperate Europe, where it historically grew through grain fields and became known as Bachelor’s Button. Its flower heads are typically around 2–3 cm across, with thin, papery petals that can appear in vivid blue, muted purple or white. Its aroma is delicate, and flavour is very mild.
In European herbal tradition, cornflower petals were collected and dried for infusions and external preparations. Historical records describe their use in traditional eye preparations, although these applications do not establish therapeutic benefits or suitability for modern medical use. Cornflower has also been valued for adding natural colour to herbal blends.[1]
At Austral Herbs, we supply cut cornflower petals in blue, purple and white, alongside an uncut certified organic blue variant. Our cornflower is processed in a HACCP-certified facility, with formats suited to tea, beverage, beauty, décor and creative applications.
Traditional Uses of Cornflower
Cornflower petals have a long history in European herbal preparations and decorative applications. Their naturally occurring pigments and other plant compounds have also attracted scientific interest, particularly in research involving cornflower extracts.
Naturally Occurring Compounds Studied for Antioxidant Activity
Cornflower’s blue petals draw their colour from anthocyanins, a pigment group built on cyanidin. Some research has investigated these naturally occurring compounds for antioxidant activity, although evidence relating to cornflower specifically remains limited and mixed.[1] However, these findings do not establish antioxidant health benefits from consuming dried cornflower petals.[2]
Traditionally Used in European Herbal Preparations
In European folk practice, dried cornflower petals were used in herbal infusions and traditional external preparations, particularly those associated with eye care. Historical records from Central and Eastern Europe document these applications, reflecting the flower’s longstanding place in traditional herbal practices. These historical uses should not be interpreted as evidence of clinical effectiveness.[1]

What Industries Can Cornflower Be Used In?
Cornflower is valued across several industries for its vibrant colour, delicate structure and mild flavour. From tea blending and botanical beverages to skincare and decorative products, its petals can add visual interest without contributing a strong taste or aroma.
Tea
Tea blenders use cornflower petals to add colour and visual interest to loose-leaf blends, introducing blue, purple or white petals among green and black tea leaves. Their mild flavour generally has little influence on the overall taste, making them a useful option for blends where other ingredients provide the primary flavour. The 4–10 mm cut may suit teabag production, while uncut petals offer visual appeal in presentation tins and loose-leaf teas.

Creative
Crafters and floral studios incorporate cornflower petals into confetti, pressed-flower art, resin castings and handmade paper. Their thin, delicate structure makes them an attractive option for projects where natural shapes and botanical colour add decorative detail. Uncut petals retain more of their natural form, while purple and white variants offer softer colour options than classic blue.
Home Décor
Interior designers and dried-flower makers use cornflower petals in potpourri, botanical wall art, decorative displays and table styling. Their distinctive colours can add contrast to dried arrangements, with blue and white petals creating lighter combinations and purple offering a deeper tone. Keeping finished arrangements away from direct sunlight may help reduce colour fading over time.
Beauty & Makeup
Cosmetic formulators may incorporate cornflower petals into bath soaks, salt blends, face masks and soap bars for their decorative appearance. The petals can provide visible botanical detail in finished products, with cut formats offering smaller pieces for different formulations. Suitability depends on the finished product, petal size, intended use and relevant safety assessments.
Beverage Manufacturing
Beverage manufacturers may use cornflower petals in botanical sodas, cordials, ready-to-drink infusions and decorative beverage applications. Their mild flavour makes them ideal for formulations where other ingredients provide the primary taste, while their colourful petals can contribute to the visuals of the final product.

Shop Our Cornflower Collection
Our cornflower collection includes conventional blue, purple and white cut petals, alongside certified organic uncut blue petals. Each variant offers different options for colour, presentation and intended application, with availability varying by product.
Cornflower Petals - Purple
The purple variant offers a softer alternative when blue provides too much contrast against a pale base. Cut to a natural size of 4–10 mm, it may suit tea blending, confectionery decoration and creative applications where a more muted botanical colour is preferred. This is a conventional, non-certified organic line.

These petals suit tea brands, crafters and décor makers working with a lighter colour palette, while also standing out against darker tea leaves or coloured bath salts. Cut to a natural size of 4–10 mm, this is a conventional, non-certified organic variant.

What is the difference between the blue, purple and white petals?
The main difference is colour, although format and certification also vary. Blue provides vibrant contrast, white offers a softer appearance, and purple adds a more muted tone. All three come from the same plant species and generally have a mild flavour.
Should I order cut or uncut petals?
Cut petals are generally suited to blending and applications requiring smaller botanical pieces, while uncut petals are ideal when visual presentation matters. The 4–10 mm cut may suit teabag production, while uncut petals retain more of their natural shape for loose-leaf teas, decorative blends and creative applications.
What does cornflower tea taste like?
Cornflower has a very mild flavour, with a faint hay-like note and subtle sweetness. It is usually selected for colour and visual interest rather than to change the flavour profile of a tea blend.
How should cornflower petals be stored?
Store cornflower petals in a sealed container in a cool, dry place away from direct sunlight. These conditions may help maintain their colour and quality over time. Handle uncut petals carefully, as their delicate structure makes them susceptible to breakage.
Are cornflower petals edible?
Cornflower petals are commonly used in culinary applications, including tea blends and decorative food garnishes. However, make sure to confirm that the specific product is suitable for food use and meets applicable food safety requirements before incorporating it into finished products.
