The big blue and white ones are campanulas (Campanula persicifolia). The little blue one to the left is Campanula rotundifolia. The purple one under it is Geranium 'Patricia', above it to the left some Salvia verticillata 'Purple Rain' (unfortunately the photo does not render how beautiful it is in life).
The two wine-red ponpons near to it are a brook thistle (Cirsium rivulare). Below, a hydrangea is about to bloom (Hydrangea arborescens 'Annabella'). In the middle, below, a Hosta (to the right there are two more Hosta flowers as well). Behind it the wood spurge (Euphorbia amygdaloides 'Purpurea') that is still blooming.
Beside it, a handful of Heuchera coming from the garden of my mother-in-law, of which I do not know the exact name. To the right, a Solomon’s seal (Polygonatum multiflorum 'Variegatum'). And finally, two decorative bulbs: a big purple Allium atropurpureum (uncorrectly called Allium atropureum on its paper-bag), while the two tousled ones are Allium vineale 'Hair' (spelled uncorrectly again as Allium 'Fineale Hair' on their bags).
