The edible petals of herbal roses make delicious conserves and are used in salads and desserts. Herbal roses prefer full sun and most of the herbal roses flower only once a year, but abundantly over a month.
Old roses are very tough and need not be pruned. If you wish to prune them for shaping, do so immediately after flowering ceases as they flower on ripe wood. Harvest herbal roses when they have just opened, on sunny mornings as soon as the dew has dried. To dry, spread the flowers on flyscreen covered frames out of direct sunlight.
The single-flowered varieties of Rugosa rose with their abundant, repeat flowering habit, and tolerance of cold and seaside locations, bear clusters of plum sized hips that are excellent for use in syrups and teas. Harvest the hips when fully coloured and dry in the same way as the flowers.
