Rhode Island: Violet

Some species are acaulescent, which means that they do not have stem. They develop leaves in the form of rosette directly from the ground. Other species have short stem with alternately arranged leaves. Flower is fragrant due to compounds known as terpenes and ionone. Scent of some violas is so strong that it desensitizes nose and prevents detection of other odors. Young leaves and flowers are edible. They can be used raw (as a part of salads), cooked (in the sauces and jellies) and for decoration of cakes and other desserts.
