Explorer Roses
Very hardy roses with exceptional flowering habits. All are named after famous (and not so famous!) Canadian explorers. These are the most popular cold-hardy roses in the world.

These roses were originally developed at the Ottawa research station, with new varieties being introduced from the research station in l'Assomption PQ. Both research programs were closed about a decade ago.

Explorer roses need no winter protection. Your tax dollars at work, and worth every penny!
