Just found these two at garlandnursery.com in Corvallis, and they're now in my garden. They always seem to have one or two oddball items like this, and always in exactly the same place in one of their greenhouses.

I think we need a forum for Chilean or South American plants on here, I seem to be adding more and more of them to my garden!

I've grown A. microphylla in many gardens, this is my first try with other species. I know these two are less hardy, but at least one of them is thriving at Sebright in Salem.
