Wow, comments! I love y'all. :) And it's so good to hear from other folks having fun in their gardens.
Anti-V sent this link along in email to confirm Nina's guess about the blue flower.
It's called Glory in the Snow. There's only one problem. I don't remember planting them, and I don't remember it being there in the years before so it isn't old homeowner plantings. And there's too many of them to have been squirrel'd in.
My memory is clearly starting to fail! Good thing I'm blogging much of it down.
More on the trip to Richters and family visits later.
