Still one of my favorites! Emerald Fire = boissierieanum x Calurum. I used Calurum var grandiflora to make this one, which is a lighter colored form of Phrag. Calurum. My intent was to create some "white" Phrags. I actually like that it is not all white, but has some pink accent colors.
So nice, every time I look at it, I want one. To bad that Phragmipedium are not often seen over here. Few vendors in Europe have them at all, and Calurum or Sedenii and other 'old' crosses are rarely seen. But this - and other! - is addictive!!!
