      At least one Web page from a gardener cites honey bees visiting morning glories:  http://www.agardenforthehouse.com/2012/04/can-you-help-the-honey-bees/ .  Not clear though whether they are collecting nectar or pollen, and whether they are pollinating.

      Good Point David, I can envision a number of western species that fall into that category, but out East... I can think of trumpet honeysuckle (clearly geared towards hummingbirds) but am wondering if things like the native morning glories are not wide throated enough to permit honey bees to enter. I have seen plenty of Bombus, Melitoma, and Peponapis on them, but don't recall honey bees....but I may be simply discounting them.

      Probably any of the flowers with corolla tubes longer than about 6 mm will be pollinated by long-tongued native bees.  Honey bees' tongues are about 5 mm.

      I have been working with the National Zoo here in Washington D.C. as a bee adviser.   As part of their new outdoor bee and pollinator exhibit they would like to have a set of plants that are only pollinated by native bees and would not be pollinated by honeybees. 

      I can think of plants that are inefficiently pollinated by honeybees, but because of my weakness in pollination biology am not sure of what plants are ONLY pollinated by native bee species.

      Perhaps some of the orchids?  Super tiny flowers?  Native Wisterias?  I am grasping here....so help me out.

      Are any flowers actually always avoided by honeybees because of the composition of nectar/pollen as opposed to simply the flower's physical characteristics?

      I have copied Elaine Soulanille from the zoo this email so go ahead and copy her on replies.

      I sink back upon the ground, expecting to die. A voice speaks out of my ear, You are not
      going to die, you are being changed into a zebra. You will have black and white stripes
      up and down your back and you will love people as you do not now. That is why you
      will be changed into a zebra that people will tame and exhibit in a zoo. You will be a
      favorite among children and you will love the children in return whom you do not love
      now. Zoo keepers will make a pet of you because of your round, sad eyes and musical
      bray, and you will love your keeper as you do not now. All is well, then, I tell myself
      silently, listening to the voice in my ear speak to me of my future. And what will happen
      to you, voice in my ear, I ask silently, and the answer comes at once: I will be your
      gentle, musical bray that will help you as a zebra all your days. I will mediate between
      the world and you, and I will learn to love you as a zebra whom I did not love as a
      human being.
