Rosaceae

The ‘Frontenac’ Hardy Rose is a Canadian shrub rose from the Explorer series, known for its excellent hardiness and abundant blooms. It forms a vigorous shrub with an upright and slightly spreading habit, producing generous clusters of deep raspberry-pink semi-double flowers. Its medium green foliage shows good disease resistance and highlights the intensity of the blossoms. Blooming profusely from early summer until the first frosts, it is perfect for beds, informal hedges, or isolated plantings where it provides structure and lasting color. Very tolerant of cold climates, the ‘Frontenac’ Hardy Rose attracts pollinators and is a reliable choice for northern gardens seeking robustness, prolonged flowering, and moderate maintenance in full sun.
