Edible parts of Sweet Violet : Young leaves and flower buds - raw or cooked. Usually available all through the winter. The leaves have a very mild flavour, though they soon become quite tough as they grow older. They make a very good salad, their mild flavour enabling them to be used in bulk whilst other stronger-tasting leaves can then be added to give more flavour. When added to soup they thicken it in much the same way as okra. Also used as a flavouring in puddings etc. A tea can be made from the leaves. Flowers - raw. Used to decorate salads and desserts. A sweet mild flavour with a delicate perfume, the flowers are an especially welcome decoration for the salad bowl since they are available in late winter. The flowers are also used fresh to flavour and colour confectionery. A soothing tea can be made from the leaves and flowers. A leaf extract is used to flavour sweets, baked goods and ice cream.
Other uses of the Sweet Violet : An essential oil from the flowers and leaves is used in perfumery. 1000kg of leaves produces about 300 - 400g absolute. The flowers are used to flavour breath fresheners. A pigment extracted from the flowers is used as a litmus to test for acids and alkalines. Plants can be grown as a ground cover when spaced about 30cm apart each way. They make an effective weed-excluding cover.
Propagation of Sweet Violet : Seed - best sown in the autumn in a cold frame. The seed requires a period of cold stratification and the germination of stored seed can be erratic. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the summer. Division in the autumn or just after flowering. Larger divisions can be planted out direct into their permanent positions, though we have found that it is best to pot up smaller divisions and grow them on in light shade in a greenhouse or cold frame until they are growing away well. Plant them out in the summer or the following spring.
