Dryas octopetala is a very common and beautiful plant of alpine slopes in this area, and in addition, it has the delightful habit of repeated bloom through the season.
It can also be grown fairly easily in the garden here (last photo)... why I bother with my relatively feeble effort, though, when I see them in natural splendour throughout our mountain hikes, I don't know! ??? Anyway, it is another point in its favour, as if it needed one!
