Agastache, Anise hyssop is a good one too and the birds are fond of the seeds. If you have some moisture, then Stoke's Aster is good.

I do like Rudbeckia fulgida var. fulgida, I have it as well. It has just started blooming in the last couple weeks, so it is a late one for me.

Hi..how about Heliopsis Summer Sun it would go with what you have already and it blooms forever bobby

By the way, an article on a pollinator-attracting evaluation of Stokesia laevis.

Here is a link that might be useful: Study near Macon State

Thanks Esh. I also grow Stokesia Laevis 'Silver Moon' - nice plant.

chezron, I have what I think is that rudbeckia - it's slightly taller and long flowering than hirta, and blooms later. Both are good -hirta to bloom first, then this one to bloom later. I have a TON of it if you are in the Atlanta area and want some.
My other suggestion is some hot lavender pink phlox. I have one that blooms after the cone flowers stop. It's blooming now. Joe Pye Weed, and also the brightest of the obedient plants would also work.
