Hybrid Rugosa 'Jens Munk': Svejda's Explorer Series Toughness

Part of Agriculture Canada's legendary Explorer Series, 'Jens Munk' (also known as Explorer Series Collection) was introduced in 1964 by Dr. Felicitas Svejda. Named for the 17th-century Danish navigator who searched for the Northwest Passage, this hybrid rugosa embodies the series' mission: roses that survive -35°C winters and bloom reliably in the harshest climates.

Botanical Profile

The flowers are medium pink, semi-double, and fragrant, opening in clusters from late spring through fall. The foliage is characteristically rugose—wrinkled, leathery, and deeply veined—with exceptional disease resistance. The plant forms a dense, suckering shrub 4-5 feet tall, ideal for hedges, windbreaks, and coastal plantings where salt spray defeats lesser roses. Svejda's breeding genius lay in combining the ironclad hardiness of Rosa rugosa with repeat flowering and manageable size. 'Jens Munk' doesn't just survive the North—it thrives there, a floral flag planted in frozen ground.
