At my house the hummies like the coneflower, salvia, standing cypress, daylilys, glads, rainlilys, blackberry lilys, trumpet honeysuckle (native), confederate jasmine, they will nectar at the butterfly bushes, I've seen then nectaring on gaillardia, they like the phlox, sweet william & a myriad of wildflowers. My firespike doesn't bloom until they have headed south but the butterflies love them.
