They definitely like the native penstemons. I've got two native penstemon species, but most now are crosses between the two species, as through the years the plants from seeds turned out hybrids. And the hummers love them, sometimes checking the buds out impatiently before they open! And Flame Acanthus rates really big on the hummer rating scale here! I have quite a few and they're flowering earlier than usual this year, so hummers are happy! And of course, salvias of any color, but I mostly have pinks and reds. Turks Cap, of course. Coral Honeysuckle is a favorite...mine was blooming before winter was over and still is blooming, although less in this heat. And Red Yucca is always popular when it's blooming.
