This is the Dwarf Balloon Flower Platycodon grandiflora 'Astra Blue', I happened to notice that one of the flowers has only 3 petals, whereas the rest have 4. I wonder if it's a sign of good luck, similar to a 4 leaf clover? It is growing along the east side of a small shed, and the flowers seem to turn towards it. I suspect that it might be to face the heat radiating off the wall, so I might relocate it to a new spot.
And here is a new addition, the purple coneflower Echinacea purpurea. It's currently in a pot, being moved from spot to spot trying to find the right location before planting.
