Best Roses for Quebec

A rose that comes through a Quebec winter with green canes and plump buds is usually a hardy shrub rose, not a hybrid tea. Cold-hardy choices for Quebec include Explorer roses, Meidiland shrubs, floribundas and old-fashioned roses. Hardy shrub roses need little fuss, while floribundas need protection in cold winters.

Best Roses to Grow in Quebec

Winter decides which roses last here, so cold-hardy choices include shrub roses, polyanthas, floribundas, hybrid perpetuals and many old-fashioned roses. All of them tend to be hardier than hybrid teas and grandifloras. Around Montreal the Canadian hardiness zone is 5b (a Canadian rating that does not convert to a USDA zone), and colder districts need hardier picks still.

Explorer Series Roses

These Canadian-bred shrub and climbing roses carry the names of explorers such as Champlain, Cabot and Kelsey. They are built for cold winters, which is why they suit Quebec so well. Hardy shrub roses of this kind perform well without extra winter protection, so they are a good place to start.

Meidiland Series Roses

Meidiland shrub roses have held up in cold-climate trials, though some varieties are marginal in colder districts. Check the hardiness of the specific variety before you buy. In a milder pocket near Montreal they are a sensible choice for low, easy borders.

Knock Out Roses

Knock Out is another hardy shrub rose that performs well without extra protection. That makes it useful where you want color without wrapping canes every November. Plant it in a spot where the shoots can grow freely and the plant keeps its natural shape.

Floribundas and Polyanthas

Both prove more winter hardy than hybrid teas, and both reward you with clusters of blooms across the season. Floribundas repeat-bloom on new wood, so they are pruned in spring once growth is active. They are a step up in tenderness from shrub roses, so give them a sheltered spot.

Hybrid Perpetuals and Old-Fashioned Roses

Hybrid perpetuals and many old-fashioned roses come through winter better than hybrid teas. Some old garden roses and ramblers flower only once a year, on last year’s wood. Prune those right after they bloom and never in early spring, or you cut off the flowers.

How to Choose a Rose for a Quebec Garden

Start with how much winter work you want to do. Hardy shrub roses ask for little winter work, while hybrid teas, floribundas and grandifloras need winter protection in cold winters. Choose only types hardy enough to survive the coldest average winter in your growing zone.

Your own garden may be colder or milder than the zone for the reference city, so a hardy variety is the safer bet.

For repeat-blooming roses (hybrid teas, floribundas, modern shrub roses), pruning falls in April and May, and it can also be done in March once you see active growth. In Montreal, the last spring frost falls on average around May 6. That is a midpoint, so in half of years the frost comes later. This province has no local rose-timing page, so the dates follow the nearest comparable climate. Confirm them with a local garden centre or rose society.

Which Roses Suit Different Parts of Quebec

Quebec is not one climate, and the choice of rose shifts as you move away from the Montreal area.

• Montreal and the St. Lawrence lowlands: The Canadian zone 5b figure applies to Montreal, not to the St. Lawrence lowlands as a whole. Floribundas and well-protected hybrid teas are workable if you will cover them each fall.
• The Laurentians and other upland districts: Spring runs behind Montreal, so wait for active growth before pruning. Lean on Explorer roses and check the hardiness of any Meidiland variety.
• Saguenay and the northern districts: Winters are harsher and the season starts later. Stick to hardy shrub and Explorer roses and skip tender types.

A sheltered corner against a wall can give a marginal rose a better chance, but it never turns a tender type into a hardy one.

Rose Buying Mistakes to Avoid in Quebec

Buying Hybrid Teas Without a Winter Plan

Hybrid teas, floribundas and grandifloras need winter protection in cold winters. Without it, canes can die back and the plant starts the next season weak. Buy them only if you are willing to cover them after the hard frosts. Otherwise choose a hardy shrub rose.

Trusting a Marginal Variety

A label that says hardy does not always mean hardy for you. Some Meidiland varieties are marginal in colder districts, and any rose rated above your zone is a gamble. Pick types suited to the coldest average winter in your growing zone, and ask the garden centre which varieties have wintered locally.

Pruning Once-Bloomers in Spring

Old garden roses, ramblers and many climbers flower once a year on last year’s wood. A spring prune removes the buds, and you get leaves but few flowers. Cut them right after they bloom instead. Repeat-blooming roses are different, since they bloom on new wood and take spring pruning well.

Where to Get Rose Advice in Quebec

The province’s agriculture ministry, MAPAQ, is the official starting point, and local growers fill in the details of your own district.

• A local garden centre can tell you which varieties have wintered well nearby, so visit before you buy bare-root roses in April or May.
• A rose society or master gardener group is useful in spring, when you are deciding what to prune and when to uncover.
• Provincial gardening groups can confirm local timing, so ask them before you start pruning.

Common Questions

When Should You Cover Roses for Winter in Quebec?

Cover them in November, in late November after hard frosts have killed the leaves. Take the cover off in May, in early May before new growth begins. It can also come off in April if spring is early.

When Should You Feed Roses in Quebec?

Feed from April through July, with August as a late fallback. Stop feeding after August, since late feeding pushes new growth that may not harden off before winter.

Can You Plant a Rose in Quebec in Summer?

Bare-root roses go in during April and May. Potted roses can go in later, so a potted plant can be set out after the bare-root season if you keep it well watered.
