Iris is a genus, which contains over 250 species of vibrant flowering plants. In fact, the name is derived from the Greek word for rainbow.
It is a perennial plant that can also be grown from bulbs. Their flowers have six lobes and are shaped in a fan-like formation. They have a narrow base, which expands into a broader portion. Some of them have "beards", which are short upright structures growing from within.
They attract many pollinating insects. Flying insects are able to land on their petals as they probe for nectar. Eventually they will fly to another blooming flower to help spread its pollen.
