Fresh flowers on a wedding or celebration cake look stunning and natural. But a cake is food, and shop-bought flowers aren't grown for eating: they're treated with plant protection products, and some species are toxic. Here's which flowers you can use on a cake, which you must avoid and how to decorate beautifully and safely.
Flowers for your celebration can be ordered together with our wedding bouquets.
Key safety rules
Why you can't just use flowers from a bouquet
Treatments. Cut flowers are grown for decoration, not food, so pesticide and fungicide residues may remain on the petals.
Toxicity. Several popular florist flowers are poisonous or irritating — even if nobody eats them, sap from the stems can get into the icing.
Hygiene. Stems, leaves and insects shouldn't touch the icing or sponge.
An arrangement beside the cake — flowers on or around the stand rather than on the icing.
FAQ
Can I put roses from a bouquet on a cake?
Only as decoration on sealed stems and a base, with no contact with the icing, removed before cutting. Don't eat those petals.
How long will fresh flowers last on a cake?
Usually 2–4 hours, so add them just before serving.
Who should decorate the cake — the florist or the baker?
Usually the florist prepares the flowers and the baker places them, following food safety rules.
