Suggested Varieties and Description of Hardy Explorer Roses
I’ve been growing Explorer roses for many years now and I can say that they are exceptionally good plants.
This is particularly true if you’re looking for a climbing rose that is hardy.
Most of these hardy Canadian roses are shrub types with a different parentage that gives them different flower shapes and growth habits. We can use them in our gardens, even warmer gardens, because of their disease resistance and exuberant growth.
Explorer Roses Are Hardy
Note that all of these Explorer roses are disease resistant to powdery mildew and blackspot. They have different levels of resistance (not uniformly resistant) to the diseases.
Explorer roses are typically hardy roses, bred in Canada for Canadian rose growing winters and conditions. These are not your basic tender rose.
Alexander MacKenzie has a shrub growth habit but the deep red blooms resemble grandiflora or hybrid tea blooms. It will survive zone 3b winter without protection.

Champlain is a short shrub reaching 3 feet tall but it blooms freely for most of the summer. The blooms are dark red and semi-double. The plant itself is disease resistant and hardy into zone 3.

It is a fully hardy yellow rose that initially opens with a high center to resemble a hybrid tea but then opens fully to expose the stamens and be a semi-double.

The only yellow in the Explorer roses series.
