The fragrant and stunningly beautiful flowers of the fava bean plant bloom from a period of weeks to a month or more, providing pollinators like bumble bees (Bombus spp.), European honeybees (Apis mellifera), and other species of native bees with nectar for a relatively long period of time.
Favas also have extra floral nectaries (see photo) that provide additional food to a number of pollinators and beneficial insects like parasitic wasps and predatory mites, ants, ladybug beetles and mites. Fava's extra-floral nectaries helps these tiny critters survive during the winter, allowing them to feed on pests the following spring.
Favas have extrafloral nectaries on its stipules, the leaf-like structures at the base of a leaf.
