And apparantly it can be grown in full sun.
It is indeed a very open location but on has to be careful. Plants which are typical woodlanders at low levels like Pyrola rotundifolia may grow very well indeed in very exposed positions on mountainsides where temperatures never become very high and where there is abundant water supply from melting snow higher up. It might prefer woodland conditions when grown at low levels in Europe.
