Brezzo Flower Pollen is the flowering element of flowers. It is contained in the stamens of the flowers and is composed of very small granules. According to the flower of origin it has a variable color: yellow, green, pink, white, red, brown. Pollen is harvested by foraging bees which, passing from flower to flower, promote pollination. The granules are then collected by the bees with their hind legs and brought to the hive. Pollen is the only protein food of bees. In the hive it plays a fundamental role in the nutrition of bee larvae, which can thus develop completely for metamorphosis.
