One of my favorite shade perennials at home blossoming right now is the Campanula ‘Samantha’.  It is tucked in between two of our Ely greenstone boulders and it is full of lavender-blue blossoms.  A compact long flowering Campanula with fragrant flowers, it blooms heavily in early summer.  It will rebloom with periodic deadheading.  I have this planted in an area that gets the morning sun.  Depending on the source, it will say it is a Zone 4 or a Zone 5.  I have had this plant here for many years so it has proven hardy here in Zone 4.

Other perennials that you can see here is Minuteman Hosta in the background, and in the foreground is a Tiarella.
