Hello Chris & All,
Chris asks:
This shrub is being advertised in the UK as being attractive to bees.  It
seems to be native to the eastern side of the US.

The common name in the U.S. is Hop-Tree or Shrubby Trefoil. The stuff grows
wild all the way to way to west Texas. The shrub/tree is listed in both of
the major books on American Honey plants.

The California Hop-Tree (ptelea crenulata) is said not to be of importance
to beekeepers but the Ptelea trifolata is said to be of importance to
beekeepers in West Texas.

My opinion is the shrub/tree is a minor nectar source.

Bob
