I have only one viburnum but I've seen them blooming heavy this spring in yards and along highways. This is 'winterthur' and is about 4 feet high.
The hot dry "no mans land" between the curb and the sidewalk is just the right spot for Gaillardia. I remember these growing at my grandparents farm house in South Dakota.
I have a love hate relationship with Spiderwort. I like it where I plant it--I don't like it when I find it in volunteering in other spots since it will crowd them out. I'm watching it engage in a battle with Day Lilys and Monarda. When I was taking this picture I caught a bee making its approach to landing.
And this weeks church flowers.
