Monofloral honey is a type of honey which is valued because it has a distinctive flavor or other attribute due to its being predominantly from the nectar of one plant species.
While there may never be an absolute monofloral type, some honeys are relatively pure due to the prodigious nectar production of a particular species, such as citrus (Orange blossom honey), or there may be little else in bloom at the time.
Beekeepers learn the predominant nectar sources of their region, and often plan harvests to keep especially fine ones separate. For example, in the southern Appalachians,sourwood honey, from a small tree that blooms late in the season, is highly regarded. Beekeepers try to remove the previously produced dark and strong flavored tulip poplarhoney, just before the sourwood bloom, so the lighter sourwood is not contaminated
