But what do you mean by "high altitude"? Can you update your information to show your location and zone?
I live in Reno, NV, elevation 5000 feet and I have that little manzanita growing in my yard. Its the only truly cold hardy manzanita I know of.

Dragon's Blood Stonecrop (there are several Stonecrops that are cold hardy), Cold hardy hens and chicks (Sempervivum), creeping thyme (Thymus serpyllum) says hardy to Zone 4 but my daughter had it growing in Zone 2b in Idaho. And of course, Kinnikinnick Manzanita.
