Here is one truly from the far reaches. From St. Paul Island in the Pribiloff's comes this diminutive bone-hardy Lilliputian member of the genus. Perfect for the rock gardener in wicked cold climates, this has it all and in scale - nice foliage with comparatively large open blueish flowers that are sweetly scented. Not too dry.  Easy.

From a 2012 collection in China by Goteborg Botanic Garden's three Henrik's including Henrik Zetterlund and his sense of humor is all over the expedition acronym. This is Polemonium chinense var. chinense based on the glabrous stems. Violet flowers, rarely white in late spring and early summer. We keep waiting for a white one.
