Himalayan Iris

It is a sight for sore eyes to see the Himlayan Iris Iris nepalensis cover whole mountainsides in spring. The violet flower has white and yellow markings.
The Iris is found all over the temperate region of the world. It takes its name from the Greek word for rainbow. Iris flowers come in many colours.
The Iris flower is formed in such a way that when a bee enters it to get the nectar, the insect will come in contact with the pollen only after passing the stigma. When the bee backs out of the flower, it will only touch the lower face of the Stigma, which is non- receptive. Thus the flower ensures that the bee doesn't pollinate it with its own pollen. Each flower is pollinated by the pollen of another.
