The following has been excerpted from Urban Flowers: Creating abundance in a small city garden, in which professional gardener and florist Carolyn Dunster imparts her knowledge to readers in regard to growing and using flowers and plants effectively in small urban spaces.

Cupcakes decorated with flowers - Edible floral treatsReal flowers can be used to flavour food, but you’re more likely to get a distinct aromatic taste if you use distilled culinary waters and essences. These are generally available in the baking areas of large supermarkets and also in Middle Eastern stores, where rosewater and orange blossom essence, in particular, are used widely in both sweet and savoury dishes. You can also buy flower syrups and cordials or make your own by boiling petals with water and sugar and then straining them well before bottling and sealing. These are perfect for making ice creams and sorbets and adding to cakes, desserts and cocktails.

Crystallizing edible blooms

For some extra floral zing, embellish your home baking with freshly picked edible flowers. You can crystallize the petals of roses, violas and pinks by painting them with egg white and dusting them with icing sugar. Leave them to dry overnight before applying another coat or two, and then put them aside to harden. Use them to decorate home-made chocolates, truffles, biscuits, cupcakes, macaroons or meringues. Serve with a flower-flavoured infusion or a sparkling floral cocktail as a toast to celebrate all that’s truly wonderful about a flower-filled life.

Simple flower and plant recipes

If you want to eat your homegrown flowers, ensure they’re organically grown and not treated with any chemicals, and don’t use foraged flowers or florist-bought blooms for cooking.

  • 225 g (8 oz) caster sugar
  • airtight spice jar or jam jar


  • Add a layer of sugar to the bottom of a jar and then add a layer of lavender flowers. Continue to layer to the top of the jar, seal with a screw lid or cork and give it a good shake.
