    According to Darwin (Chuck) bumble bees (humble bees) were the primary pollinators of heartsease (viola tricolor) and red clover (Trifolium Pratense).

        Turtlehead (Chelone obliqua) is quite similar as bumble bees must push their way into the flowers and possibly fit the architecture such that they do provide pollination. Many small natives also visit, but I wonder if they pollinate this plant.

        Sounds like an interesting exhibit and a fun challenge. 

        My favorite example of a plant only pollinated by a native due to morphological exclusion is the closed bottle gentian, Gentiana andrewsii. The petals never open broadly and it seems that only bumble bees are strong enough to force their way in to get the nectar. It's a great one to wow people with as it is very amusing to watch the bees disappear into the flower and then make their way out.
