I refuse to mess with those feeders... No way to prevent fermentation in the ga summers.
Luckily, there are plenty of plants that are happy in my yucky sand...
Any hibiscus... They like rose of Sharon just fine... I don't really have a problem with those seedlings that some people have...
Cannas are magical, especially the small flowered varieties.
Salvias do very well in my garden... I have a number of varieties...
And those cleomes... And 4 o'clock...
Also tithonia, hyacinth bean, cypress vine.... Even zinnia...
The annuals are self sowing at my house.... So... That's easy.
Also for early spring...
The native coral honeysuckle, and those Canada columbines...
And... While not native to my area...
Diclipta suberecta (Uruguay firecracker plant) which thrives in my droughty sand...
I doubt that it's any more healthy to feed those hummingbirds at feeders than to give children all the soda pop they want... So... Yay about your plan to provide them with nectar plants...
Edit:
Just checked my tumblr... Different pictures than my regular garden blog...

Flowering ginger and vitex are also draws...
Not sure how many of these southern faves will grow in the PNW, but... The more turf that you take out in favor of flowers... Is sure to result in increased hummingbird/butterfly activity...
