Wild rose (Rosa species)
The Wild Rose shrub grows 60 centimeters to 2.5 meters (24 inches to 8 feet) high. Larger stems are usually densely covered with straight prickles. It has alternate, sharply serrated edged leaves with 3-7 oval or slightly spear-head shaped leaflets per leaf. Its oval to pear-shaped flowers may be red, pink, or yellow (occasionally white) and typically have five petals. Younger flowers are typically darker in color. Its elongated or round fruit, called rose hip, stays on the shrub year-round. All species of roses are edible.
Edible Parts: The flowers and buds are edible raw or boiled. In an emergency, you can peel and eat the young shoots. You can boil fresh, young leaves in water to make a tea. After the flower petals fall, eat the rose hips (remove any hairs and seeds in the center); the pulp is highly nutritious and an excellent source of vitamin C. Crush or grind dried rose hips to make flour. The dried flowers can be eaten to help heartburn.
Note: Eat only the outer portion of the fruit as the seeds of some species are quite prickly and can cause internal distress.
