The bearded iris flowers have six petals. Three of the petals, called standards grow up, while the remaining three, called falls hang down. The bearded iris flower gets its name from the falls, which have a ‘beard’ of fuzz down the center. The bearded iris flowers bloom in the late spring through early summer. Some bearded iris flowers will even re-bloom late in the summer, which lasts long into the fall months. This second bloom is not as showy as the first one.
