It is a narrow headline of this thread! Can't discern the difference between A. rubra and A. alpina. We did discuss that in another thread once, didn't we? I said narrow because I don't know where to put my pictures - I'm afraid of messing your thread up, Cohan ;)
Although I don't know A rubra, I am familiar with A. alpina and Arctostaphylos uva-ursi. But your pictures Cohan, reminds me very much of the homely stuff. However do A rubra prefere more alkaline soil as it grows along Dryas?
Here are some pictures of Arctous alpina from "my place". Here it grows with Loiseleuria procumbens, Empetrum nigrum ssp hermafroditum, Vaccinium vitis-idaea, Betula nana and lichen on poor sandy moraine soil.
