Hummingbird flowers have nectar sugar types and concentrations different from bee-pollinated ones; it would be interesting to compare this in Castilleja species to see if the reward is of intermediate type.
Some Acanthaceae pollinated by hummingbirds with strongly curved beaks exhibit strongly curved long-tubed flowers which probably evolved from straight-tubed hummingbird flowers (McDade, 1992).
Classic hummingbird flowers have mostly red, odorless, trumpet-shaped blossoms that limit competition from insects.
Aviaries listed here are planted with hummingbird flowers you can grow in your garden; the birds breed in both places, so you might see nests.
