At last (late July – early August) the green-headed coneflowers (GHCF) — Rudbeckia lacinata — are blooming.
By now (08/01/14) the spring bloom of the garden is almost totally gone. The boneset is blooming throughout and the GHCF are standing tall at the back. (In another post I’ll discuss the current “weedy” state of the garden.)
The Garden as of 08/01/14
Whereas the Monarda attracted large bees, the GHCF attacts tiny bees. Here’s a view of the GHCF closer up in late July. Although there are a swarm of insects on the flowers, you can’t make them out in this photo.
Green-headed Coneflower Closer Up
In this REALLY close-up view, not quite in focus, you can see 3 little bees if you look carefully.

Finally, in this short video, you can see some bees buzzing around the flowers (you may need to watch it a couple of times to be sure to catch the bees — if you’ve ever had a visual field test this is a little bit like that):
FROM WEEDS TO BEES 
Beautiful pictures, Robin! Did you plant all those GHCFs or did they spread by themselves? I can’t get my purple coneflower to multiply.
