The aroma, taste and color of honey differ in each area because each area has a unique set of flowers.
Honeybees fly in the radius of 1-2 km to collect nectar. If over 50% of that area is covered by a single type of flower, then honey collected from that area is called mono-floral honey.
The name is attributed to that source, like Sidr honey, Jamun honey, eucalyptus honey, ajwain honey, litchi honey, mustard honey, and clover honey etc.
It is always wise to ask for different types of honey because the commercial synthetic honey brands can not give you varieties of honey.
