Greg:
 
Yes, the cotton plants grown commercially in the U.S. for fiber have
multiple nectaries and are often good nectar producers and often not.
There are three nectaries below the sepals, three above the sepals (below
the petals) and they also secrete nectar at the base of the bloom which
the are able to access in late evening when the bloom turns from white to
pink and shrinks.
 
Problem:  Researchers at the land grant universities have bred cotton
varieties that produce less nectar for the obvious reason of wanting a
less insect attractive plant.  Since cotton does not economically benefit
from entomophilic activity the nectar only serves to attract unwanted
creatures.  Still, some varieties of cotton remain prolific nectar
producers.
 
Cotton honey (in Texas) is water white and typically very low in moisture
content due to the dryness of the season in which cotton blooms.  I think
CA cotton honey is ELA.
