What varieties of roses winter without shelter in Irkutsk?
Unfortunately for Irkutsk, completely frost-resistant varieties have not yet been bred. But about non-covering species of roses do not forget. Yes, they are perhaps simpler in appearance than their noble relatives, but they surpass them in their unpretentiousness, frost resistance, and sometimes their aroma. There are three types of roses: prickly, wrinkled and dog. The first two species are widely used in the selection of garden and park roses. But all types are widely used in urban and park gardening. With these species wonderful hybrids have already been created, with terry flowers of various shades and the possibility of repeated flowering. When choosing hybrids of these roses for a non-covering garden, see frost resistance index 2-4, no more.
