Hi:
This reference may be of some help to you,it is from
"Plants for Beekeeping in Canada and the northern USA, by Jane Ramsay,
published 1987 by IBRA p.43 :
"Cichorium intybus L.
common chicory, blue daisy, blue sailors, wild succory...
Value for honey:  HP3 (honey potential=51-100kg/ha); plants may close up in
the afternoons and so yields N in the mornings only; surplus H has been
obtained where this is grown on a field scale for roots or seeds (e.g..
England and Michigan); one of the most attractive plants to bees.
Honey: is yellowish-green in colour; flavour is pleasant and has a
coffee-chicory taste
Notes: cultivated as a crop for roots or green fodder in some countries, but
is a noxious weed in some provinces of Canada."
Frank C. Pellett, American Honey Plants ,(1977, Dadant & Sons) has a similar
write-up, p. 105.
