Wild Roses

SCIENTIFIC NAME

DESCRIPTION

Wild roses have been used by people for centuries, provide food for pollinators, birds and mammals and are even the provincial flower of Alberta. Discover more about the uses, growing requirements and learn all about some Canadian species of this much-loved plant.

Native roses have pink blossoms, ranging from very pale to deep tones. They typically bloom around the end of June or early July. Their stems usually have thorns and their compound leaves (comprising several small leaflets) are arranged alternately along the stem. They often have a bushy appearance and interesting fall colour.

RANGE

HABITAT

Wild Roses prefer to be in sun, well-drained soil and water at the base of the plant in the mornings. In the spring, cut back deadwood but leave living canes as they flower on older stems.

PRIMARY ECOSYSTEM ROLES

The pollen on the wild rose’s many bright yellow anthers are a valued food source for many beneficial insects, including bees. Rose hips are a winter food for birds and mammals such as waxwings, pine grosbeaks, grouse, rabbits, coyotes and skunks.

Uses

Rose hips

Roses have been valued by people for centuries. Aboriginals are reputed to have used the roots as an ointment for sore eyes, and the wood of the plant for arrows. As food, rose hips are nourishing with their high vitamin C content and antioxidants, along with other nutrients such as zinc. They were used to treat scurvy, numerous infections and to promote digestion. You can pick the ripe red hips in the fall - some wait until after the first frost - to nibble on or to make a tea. While the seeds are edible, they don’t taste overly great and can be cut or strained out. Some species are fleshier than others. Rose hips have also been used in baked goods and puddings, and their pectin has been used as a thickener.

Rose petals are also edible and can be sprinkled into salads — a feast for the eye and a conversation starter! They can also be made into jams, jellies, vinegars and syrups. Remove the white base of the petal as it can be bitter. Candied rose petals are added to cakes for both decoration and consumption.

(Caution: We are not recommending the use of these plants for medicinal or food purposes. Many plants are poisonous or harmful if eaten or used externally. The information on food and medicinal value is only added for interest. This information hasbeen gathered from books and its accuracy has not been tested.)

Propagation

Collect rose hips once they are ripe (usually red or orange in colour). Remove the seeds and gently rub the plumpest with sandpaper. Plant immediately and watch for seedlings the following spring. According to William Cullina in his book Native Trees, Shrubs and Vines, “powdery mildew is usually not a severe problem in the garden and in the wild, but it can get pretty bad under irrigation in the nursery.” He therefore recommends keeping them in an open spot that gets sun and good air circulation, and watering in the mornings.

You can also start new plants by digging up new shoots that spread from the mother plant, or from cuttings, although some find this less successful than using seeds.

Care

These plants don’t usually require much assistance once established. Generally wild roses prefer full sun and well-drained soil although some will manage in partial shade. In the spring, cut back deadwood but leave living canes as they flower on older stems.
