Roses for Northern Climates
Garden correspondent Allan Armitage visited the Montreal Botanic Garden in Canada, where horticulturist Claire Laberge showed him some Best Bets for selecting roses that thrive in northern climates.
'Mme. Fernandel' grows well in colder climates, but needs to be protected during the winter. It should be pruned back to a height of about 1 foot and its budding points must be planted 2 inches underground. 'Mme. Fernandel' should also be covered with a blanket during the winter. This protects against UVA rays and reduces stress on the plant by preventing the temperature from fluctuating.
'John Davis' is a fast-growing and hardy shrub rose. It doesn't require much maintenance and grows to about 7 feet with branches that cascade down.
Another example of a hardy shrub rose, 'William Baffin' is a vigorous climber, growing to a height of about 7 to 10 feet. It doesn't need much pruning and winter protection is not necessary, making it an excellent choice for northern climates.
'Louis Jolliet' is a winter hardy low-growing shrub rose. It flowers almost continuously from June to the end of September and grows to a width of about 4 feet. Its low height makes it a nice plant to put in front of a fence.
'Frontenac' is another hardy shrub rose. It grows to a height of about 3 to 5 feet and produces more blooms than almost any other rose.
Like many of the other shrub roses, 'J.P. Connell' is a vigorous grower and can survive the winter without protection.
'Sympathie' is a climbing rose from Germany. It is not as winter-hardy as some of the other shrub roses and does require winter protection. Like 'Mme. Fernandel', this rose needs to be covered with a blanket through the winter conditions.
