Hi Deb,
I don't have my garden set up the way I want for the hummingbirds so the feeders are still the magnets ~
But they really like the Turk's Cap (Malvaviscus drummondii), Salvias and Agastaches, along with the Trumpet Vine (Campsis radicans) that grows wild. In the springtime they show up in April around the time the Coral Honeysuckle is blooming (It's a vine that also grows wild here) and they love it too.
Hummingbirds are highly attracted to the color red, so nectar plants that bloom red are a good choice. A couple of years ago I bought some red Penstemon from a big box store thinking the hummingbirds would like it but they never touched it. I don't know if it was because it was a hybrid that didn't have nectar or what? I may try again, from seed.
A couple of things I really want to grow for the hummingbires but don't have yet are:
Standing Cypress (Ipomopsis rubra)
Indian Pink (Spigelia marilandica)
