Hawkmoths also like deep-tubed white flowers, that produce scent at night. Bees generally don't visit such flowers, although there are exceptions. Flowers with short tubes or no tubes are more likely to attract a variety of bees. Members of the daisy family, Compositae, often attract lots of bees. Again, avoid the double varieties.
Sunflowers attract lots of native bees.
Members of the mint family are also attractive to many long-tongued.bees. Their nectar is the main attractant. Some leaf-cutting bees are attracted to members of the legume family, particularly clovers, and sweet clovers. I've seen carpenter bees en masse on Wisteria in the Boston area. Wisteria flowers require a large bee pollinator.
