Looks like Polemonium caeruleum album. Common name Jacobs Ladder. http://images.google.com/images?q=P...1I7SUNA_en-GB&um=1&ie=UTF-8&sa=N&hl=en&tab=wi
Perfect! I knew this plant from my Siberian life. But there it was deep blue. And the Russian name for it, "sinyuha", means "blue". For some reason, blue flowers prefer to be blond here in Utah. Clematis, which is blue in neighboring Colorado, is also white here. Thank you, Silver!
