Re: Shade ground cover nectar
English ivy is #1 bee-friendly shade tolerant late bloomer here but probably you do not want it (invasive). Winter heath and Christmas rose (hellebore) can be grown in part shade but I donít know whether they start blooming in fall or wait until early spring in your Zone. Not a ground cover, but Japanese anemone in part shade can attract honey bees. I have seen autumn crocus in part shade and fall blooming hardy cyclamen in deep shade (not quite sure how attractive they are to honey bees).
