This is a bit tangential...
A while ago, I used the Koppen Geiger map as a starting point to help write a report on the feasibility of green roofs in various states. Lately, I've been using the map in rosebreeding to help me decide which rose species I might purchase that should work well in my climate. It's not a perfect climate tool, but it's a good guide. Now, if I only I could acquire those harder to find species! ... sification

Hi Sarah!

The American Rose Trials for Sustainability ( uses this system too for regional awards. The combination of temperature and precipitation patterns seems to make it more useful than just the minimum coldest temperature like for the USDA Cold Hardiness zones

Which climate are you located in and which species are you excited to acquire?

Hi David,
I'm in Climate Csb, but since I have most of the native roses that fit that climate from Washington, I was looking to northern Spain and northern Portugal as a guide. And because Csb is so small outside of the pacific northwest I might need to branch in Csa to include Coastal Mediterranean regions and Turkey. While they don't all fit those climates perfectly, I'm interested in R. beggeriana; R. phoenicia; R. pendulina oxyodon; R. hemisphaerica var. rapinii and R. hirtissima.
