I'll second your enthusiasm for lantana, natvrabit. Also looking fabulous in my yard despite neglect, and attracting multiple dozens of butterflies, are my chinese abelia bushes (Abelia chinensis). If you've got a sunny spot for a large, somewhat floppy shrub that produces clusters of fragrant white flowers until frost, consider this butterfly magnet. Another nonnative that is blooming sweetly fragrant white flowers right now is my Seven Sons Tree (Heptacodium miconioides); this is also bringing in the butterflies.
My Cardinal Flowers and Great Blue Lobelias are also looking fine and bringing in the pollinators, along with Swamp Milkweed and Joe Pye Weed, all natives that I would never garden without. The goldenrods are starting to bloom, the buds on the asters are swelling, and my pineapple sage is just starting to show signs of flower buds. This herb will keep migrating hummingbirds happy with its tubular red flowers as they pass through before our first hard frost.
Neglected to mention my Joe Pye and Milkweed and some others. Beautiful display they do produce of both flowers and benefit of winged friends!
Fall can't arrive soon enough for me!
