Edible flowers add colour, flavour and texture to savoury and sweet dishes, as well as cordials, oils and butters. A wide range of annuals and perennial edible flowers can be grown in the garden from early spring to late autumn. Children can be encouraged to take an active interest in growing and preparing food through edible flowers.
When collecting flowers for eating, keep the following in mind;
Home-grown flowers, free from pesticides and soiling by dogs and other pets are best. Edible flowers are offered for sale but only use those labelled for ‘culinary purposes’ as these will have been grown in ways that ensure any pesticide residues are at acceptible. Shop or garden centre bought flowering plants should be grown on for at least three months to reduce the risk of pesticide residues and only harvest subsequent flowerings. Many garden favourites are edible and a few are listed below:-
Alpine pinks (Dianthus) – a clove-like flavour ideal for adding to cakes as flavoured sugar, oils and vinegarsBergamot (Monardia didyma) – a strong spicy scent, makes good tea and compliments bacon, poultry, rice and pastaChrysanthemum (Chrysanthemum) – petals flavour and colour cream soups, fish chowder and egg dishes in the same way as calendulaDaisy (Bellis perennis) – not a strong flavour but petals make an interesting garnish for cakes and saladsDay lily (Hemerocallis) – add buds and flowers to stir fry, salads and soups. Crunchy with a peppery after taste but may have a laxative effect.

The whole flower, leaves, and buds can be used or just the petals for a milder flavourPot marigold (Calendula officinalis) – intense colour and a peppery taste useful in soups, stews and puddings. Petals can be dried or pickled in vinegar or added to oil or butterPrimrose (Primula vulgaris) – decorate cakes with crystallized or fresh primrose or cowslip flowers. They can be frozen in ice cubesRose (Rosa) – all roses are edible with the more fragrant roses being the best.
