A Colourful Corner

There are some mystery blue flowers and white flowers in this corner of our garden. They are growing next to a delphinium and some irises. I would be so pleased if someone can identify them for me.
Thank you so very much to the many Blip friends who commented, gave stars and hearts for my 1000th blip image yesterday. I was so chuffed at the kindness of you all. Arohanui.
