Botanica ROSES and zone questions
I have a copy of the Botanica's Roses book. It looks as though it
were published in Austrailia. They have worldwide maps of hardiness zones. I am a bit confused... Although the zones are defined the same way as the USDA zones (zone4 = -20, -30). However, the actual maps place minneapolis in zone 3. We're definitely in Zone 4. It's not the discrepancy that I'm concerned about. There are several roses that Botanica places as zone 4 hardy that fall into categories that are normally not considered zone 4. What I'm wondering is if I would be unwise to consider these "midling hardy" and thus not worry about doing a full Minnesota tip, and instead use a less involved method like mounding, and surrounding the bush with straw in a chicken-wire cage? OR... Should I consder these the more likely to survive even with a minnesota tip? (over those that are listed 5 and 6) Any opinions? -Mark |

Any opinions? I am without the Botanica rose book, but if you had a question about a particular variety, perhaps someone could offer an experience or opinion on its hardiness in zone 4. If it needs to be buried for the winter it will grow as an annual or not at all in my z4a garden. Regards, Charles -- Charles Perry Reply to: ** A balanced diet is a cookie in each hand ** |
