Champlain
A Legendary Zone-3 Red Rose Bred to Survive Canadian Winters
Champlain Rose (Rosa 'Champlain') is one of the toughest red roses ever bred — part of the Explorer Series developed by Agriculture Canada specifically for cold-climate survival. It produces velvety, deep-red blooms in flush after flush from early summer to frost on a rounded, own-root shrub, and it's hardy to USDA zone 3 with no winter protection. Disease-resistant and dependable, it's a Minnesota classic. Whether you want a no-fuss red rose in a Maple Grove bed, a hardy flowering shrub in an Edina border, or a mass planting in Woodbury, Champlain is built to last.

Champlain Rose Uses in Minnesota Landscapes
Bulletproof Red Flowering Shrub
Champlain is about as tough as roses get — zone-3 hardy, own-root, and disease-resistant. Plant it in a bed or foundation planting for months of velvety red bloom with no spraying and no winter burial.
Bold Color in a Sunny Border
Its deep red flowers anchor a sunny perennial border and pop against silver foliage or blue-flowered companions like catmint and balloon flower.
Mass Planting or Low Hedge
At under 3.5 feet, Champlain makes a glowing informal hedge or mass planting along a walk or drive. Space plants about 2.5–3 feet apart for a continuous run of red.
Best Time to Plant Champlain Rose in Minnesota
Plant in spring (May, after the ground thaws) for the longest establishment window, or in early fall (late August–mid September) so roots settle in before freeze. Avoid planting in peak summer heat, and never plant after mid-October or before spring thaw.
How to Plant Champlain Rose
- Choose a full-sun spot with good air circulation — it reduces leaf disease and maximizes bloom.
- Dig a hole twice the width of the root ball and just as deep, so the crown sits at or slightly above grade. As an own-root rose, there's no graft union to bury.
- Loosen heavy clay and mix 25–30% compost into the backfill for drainage and nutrition.
- Set the plant, backfill, and firm gently to remove air pockets; water in thoroughly.
- Build a shallow watering basin, then mulch 2–3 inches with shredded bark, kept an inch off the stems.
- Water deeply at the base — keep foliage dry to discourage blackspot.
Watering Champlain Rose in Minnesota
First Year Watering Schedule
Weeks 1–2: water deeply every 2–3 days. Month 1–2: about twice a week. Month 3–6: roughly weekly during active growth, more in heat, easing off when rainfall is adequate. Always water at the base in the morning so leaves dry quickly. Stop watering 2–3 weeks before the ground freezes — usually late October — so the plant hardens off for winter.
After Year One
An established Champlain needs supplemental water mainly during dry spells — a deep soak about once a week in hot, rain-free weather. Mulch keeps the roots cool and evenly moist.
Will Champlain Rose survive a Minnesota winter? Yes — it's one of the most winter-hardy red roses there is. Bred by Agriculture Canada's Explorer program for zone 3, it needs no special winter protection in the Twin Cities, and as an own-root rose it regrows true even if a severe winter kills the top.
Does it rebloom? Yes — Champlain flowers in repeated flushes from early summer to frost, especially with occasional deadheading.
Do I need to spray it? Generally no. Champlain has strong disease resistance; good sun, air flow, and base watering keep it healthy without a spray program.
How big does it get? About 2.5–3.5 feet tall and 2.5–3 feet wide — a manageable, rounded shrub for beds, borders, and foundations.
Should I prune it? A light early-spring cleanup — remove dead or weak canes after the buds swell — keeps it shapely and blooming well.

How Many Champlain Roses Do I Need?
For a continuous informal hedge or mass planting, space Champlain about 2.5–3 feet apart — its rounded 2.5–3 foot spread closes the row within two to three seasons:
| Run Length | Plants Needed (2.5–3 ft spacing) |
| 10 feet | 4 |
| 20 feet | 7–8 |
| 30 feet | 11 |
| 40 feet | 14–15 |
As a bed accent, give a single plant a 3-foot circle, or group 3 in a triangle at 2.5 feet apart for one solid block of red.
Champlain Rose Season-by-Season in Minnesota
- Spring: Foliage breaks dormancy reliably even after zone-4 winters — no uncovering or unburying required; prune out any winter-killed tips as buds swell.
- Summer: Flush after flush of velvety deep-red double blooms from June onward — the Explorer breeding shows in how steadily it repeats.
- Fall: Bloom continues to frost, with red flowers holding color well in cool September and October weather.
- Winter: Fully dormant and zone-3 hardy — no protection needed in the Twin Cities, and the own-root crown regrows true even after a brutal winter.

Is Champlain Rose Right for Your Yard?
Champlain thrives in full sun (6+ hours) with good air circulation and well-drained, compost-amended soil — and unlike most red roses, it asks for zero winter protection in the Twin Cities. It's a fit for nearly any sunny Minnesota bed. It's not a fit if your spot is shady or heavily browsed by deer — deer resistance is low, so plan on repellent or fencing in high-pressure areas.
