Mustard belongs to the family of “Cruciferae” and popularly used in Indian cooking. India is number one in production of mustard. Mustard gives edible oil which is used as cooking in India. Its pollen is sticky, unlikely to be windborne and the mustard flowers are highly attractive to honey bees. Honey bees readily collect nectar and pollen from these flowers and spend 4.6 to 7.0 seconds per flower. The sugars in nectar do not contain sucrose, but have large amounts of glucose compared to fructose, indicating that the resulting honey will tend to granulate. The flower produces abundant nectar, and can be more attractive than red or white clover. Many mustard species grow and bloom in the cool climates or seasons, the plants may come into bloom at temperatures below 55°F, making them unavailable to honey bees at those temperatures.
