golden st. john's wort, hypericum frondosum, will bloom for that long a period. they are not long-lived shrubs but usually leave you some seedlings afterward, though i don't consider it weedy. i grew it some years ago in sun from morning to about 1:00p.m. it was semi-evergreen here but would be deciduous in your zone. nice foliage, flowers and seedpods and very attractive to bees and butterflies.

welcome to NC! ok- as far as the honeysuckles the one you want to avoid is the japanese one, lonicera japonica. you can plant coral honeysuckle which is vigorous, but not invasive, and unfortunately not fragrant. it's lonicera sempervirens. it's a gorgeous coral red with yellowy throats that the hummers adore, and blooms heavily in spring then on & off all summer through fall. there are some yellow flowered cultivars of it. there are some other honeysuckles and i'm sorry i can't recall the names, that look a bit more like the jap kind, but are flushed with pink and gold and behave well and have fragrance that the hummers enjoy. campsis radicans, trumpet vine-aka cow itch-aka trumpet creeper is a native vine, but it is pretty invasive. i have it on my prop and let it grow up into one tree for the hummers, but keep the rest mowed off at the ground. it's like maypop- it comes up far and wide form the original from underground runners. cross vine- bignonia capreolata, is semi-well behaved. it's a native, too- and it's everywhere for me, and hard to eradicate where you don't want. it likes to climb high and flower- it flowers at about 40-60' in my trees. i think the improved versions like tangerine may flower more profusely for you than the straight species. hummers love both cross and trumpet vine, and i have both growing up big trees and flowering very successfully. they also like carolina jessamine, another native that can get a bit unruly. it's yellow, unlike the others, and so it could offer some contrast. another thing you may not have considered for hummers, is coral bells, heuchera species (look for the ones with red or pink bells- so many now have smaller dingy white flowers). and most of the salvias are magnets, too, even the blue ones like guaranitica. they like annuals like petunias, morning glories and million bells, too. more uncommon vines like manettia and mina lobata tickle them for later in the year. all that said, i'd be cautious about planning to plant too much this year though, with the drought. the likelihood of it continuing is too great, and water too scare to water much. if you are going to plant, do it soon while the earth is still moist and the things can get well established before it gets too dry. even with that, there's a good chance you'll lose much of what you plant now. i think i'd be content to get 2 or 3 feeders and hang those to draw in the hummers this year. best of luck with your gardens!

One of the Dropmore Scarlet honeysuckles on my brother`s ranch by Pincher Creek does quite well - gets the full blast of winter and chinook winds - doesn`t need too much trimming up in the spring. Others that have been in the ground for 3 years have not fared well - either dead or nearly dead and are getting replaced with Jackmanii superba. Mandarin honeysuckle is hanging in there also. This past winter there was next to no snow cover, no snowdrifts so a lot of established perennials either didn`t make it or are really struggling.

All shade is a tough nut to crack for a hummingbird vine. you might want to explore the Lonicera, the honeysuckle group. Lonicera sempervirons will grow and bloom in the shade, although not as well as it does in sunny situations. Some of its hybrids like Dropmore Scarlet might be good to check out. Stick with New World honeysuckle. With a fair sized pot and regular water they would grow. You also might look around for Manettia cordifolia, since it is subtropical nurseries might sell it in your area. I'm not sure whether it does much in shade, but along with L. simpervirons it is a A1 hummingbird vine.
