A variety of flowering plants thrive in Ontario in gardens, ditches along roads and in the province's forests and prairies. Many of the flowering plants consist of native species. Native wild flowering plants typically require less water, and also tend to be pest and disease-resistant, making them a convenient option for almost any garden.
Prickly Wild Rose
A perennial native shrub, prickly wild rose features five-petaled blooms in June and July. Wild rose grows to 6 feet in height with prickly stems and fragrant pink flowers. After the flowers die back, smooth-skinned, red rose hips appear. Wild rose requires a lot of water, although it thrives in just about any soil type, including rocky soils, as long as the soil is well-drained. The edible rose hips contain high amounts of vitamin C and are often used in teas and jellies. The rose hips also attract a variety of birds and wildlife that use the fruit as an important food source.
An Ontario native wildflower, the pale violet, dainty flowers of the dog violet make it a popular ground cover. The plant grows in clumps up to 6 inches high, featuring heart-shaped green leaves with 1/2-inch pale purple flowers that appear in May or June. The plant thrives in meadows, moist woods and near streams. It may be added to gardens from seed in the spring or from planting divided plants in the fall. Dog violet prefers slightly acidic, well-drained soil.
The flowers of the nodding trillium may be difficult to see since they hang below the leaves, but the exquisite blooms make the challenge worthwhile. A native to Ontario, nodding trillium grows up to 10 inches in height and features three large leaves on a tall stem. The 1 1/2 inch white flowers with purple stamens appear April through June. The perennial plants thrive in cool, shady woods in slightly acidic soil.
This plant features showy clusters of small, white, daisy-like flowers that bloom in late summer or early fall. Heath aster grows up to 31 inches tall. This aster spreads easily, growing about 1 foot per year. The self-seeding plant prefers full-to-partial sun in well-drained soil. Heath aster works well in the garden, although it requires some staking unless it's planted near vegetation that it can lean on.
