What flower has a lot of nectar?

Convenience and routine determine the flowers that honeybees visit for nectar. The insects in question (Apis spp) have regular nectar- and pollen-foraging routes whose mapping out combines known and new stops. The floral nectars must be accessible since not all bees engage in nectar-robbing by piercing floral bottoms and by removing floral nectars whose removal is impeded by diminutive or protracted openings.
