Needs to keep warm growing so high up.

Cliff - Gruyere is not a green cheese ... even when 3 weeks old!  I did not expect you to have trouble identifying such a special and swiss plant  

Now Tony, surely you aren't going to tell me that that is Androsace helvetica?

I made it too easy with that last clue

Tucked into a rock crevice atop the Schilthorn.

This shouldn't be too hard, it was shown once before on SRGC Forum.

My mystery plant seems to have been the kiss of death on this otherwise active thread.  Need clues?  The plant isn't interesting?  It's a great plant with milky white flowers and not the slightest bit weedy.

The leaves appeared familiar... an Amsonia?  I looked around and found a white flowered form of Amsonia elliptica.  The flowers from both your puzzle pic and the Japanese plant look very much alike as do the leaves. Or am I wishful thinking?  I do wish your mystery plant was in my garden!

Sharon, Mark,

Yes, I grew Amsonia some years ago and this photographs certainly reminds me of it.

Well, Mark, is Sharon correct?

No, it is not an Amsonia (although it grows right next to one in my garden).  Good guess though.
I repeat my description because it is a clue, there's always a clue... now where have I heard that before?
"It's a great plant with milky white flowers and not the slightest bit weedy."

Well, it couldn't possibly be an Asclepias could it Mark?

No, but you're getting warmer

So, it's not a Vincetoxicum (=weedy)

"It's a great plant with milky white flowers and not the slightest bit weedy."

It sometimes goes by that genus (as a synonym).  It is indeed a very weedy genus, some are noxious weeds, but this beauty makes no seed and is a well-behaved perennial.  So do you know the genus and species name?  (clue - can search SRGC forum for the answer).

Cynanchum ascyrifolium

I was searching for Cynanthum and, of course, it didn't come up

Yes, it is Cynanchum ascyrifolium, well done Stephen.  Six years ago a friend visiting my garden brought this plant, had no idea about what it was.  It has since become one of my very favorite perennial plants, always neat and attractive, nothing bothers the trim foliage.  Starts flowering in May, continuous bloom through June and into July, then a second flush of flowering later in summer.  As others have reported (like forum member Kristl Walek), it sets no seed, so I never have any seedlings.  Must divide or propagate from cuttings this year.  Interesting too, is that the ends of the terminal shoots do tend to weakly twine.  Here are a few photos, with Amsonia rigida growing beside it.

And there was I thinking it as Galaplantus nonweediformus
