Cornflower – The pretty, blue flowers of cornflower (Centaurea cyanus) have a slightly spicy, clove-like flavour with a subtle sweetness. Cornflower petals look wonderful in salads. Use torn petals as a garnish, or whole flowers in fancy drinks.
Dame’s Rocket – The petals of this tall relative of mustard (Hesperis matronalis) are pink, lavender, or white, and always come in fours. Perennial Phlox looks similar, and also has edible flowers, but always have five petals. The petals (and the immature leaves) of Dame’s Rocket are worth adding to salads, but have a mild bitter flavour.
Sunflower – It’s still a little known fact that unopened sunflower (Helianthus annuus) buds can be steamed or sautéed in butter and served whole. They have an artichoke-like flavour. Alternately, the petals can be pulled from the edge of the opened flower and added to soups and salads. Their flavour is somewhat bitter.
Violet – Many varieties (Viola spp.) are suitable for decorating food. They come in a range of sweet, perfumed flavours, and a wide range of colours. Some of the tiniest violet flowers make the best additions to cakes, drinks, and salads.
