Hortico's Hardy Canadian Explorer Roses

Recommendations
Hortico Inc.

The Explorer series is a set of rose varieties specially developed to survive the Canadian winters by Agriculture and Agri-Food Canada (AAFC) at Morden Research Station in Manitoba. They are exceptional for their hardiness in Canada. They require minimal care and are environmentally friendly, needing minimal sprays. They are hardy down to -35 C with only snow as protection, are disease resistant, flower repeatedly throughout the summer, require only minimal pruning and come in a variety of colours and sizes. See also their Parkland Series.
